Oops! Crinkler has crashed.
Dump files written to dump0000_mini.dmp and dump0000_full.dmp

The created dmp files are 0 bytes in size.

When /COMPMODE:INSTANT is specified, Crinkler completes, producing a working executable.
releases/crinkler14/crinkler.exe works in all /COMPMODE options, producing a working executable.
releases/crinkler20/crinkler.exe without /COMPMODE:INSTANT crashes as above.

From the version history, Switched from Intel OpenMP to MSVC concurrency API. looks to be a suspect.

The DLL and LIB used are copied from Windows and MSVC; the test is a minimal asm:

extern _MessageBoxA@16
extern _ExitProcess@4

global _WinMainCRTStartup

_WinMainCRTStartup:
  push 0
  push msg
  push msg
  push 0
  call _MessageBoxA@16
  push 0
  call _ExitProcess@4

msg: db "hello win32",0

I used the res file to import the icon. When I use vc6 link.exe, everything is normal, but after compiling with Crinkler, the exe icon disappears, and other rc resources cannot be read.

It is possible to specify a custom linker if you are using msbuild (for example on CI) by specifying the LinkToolPath property. It works like this:

msbuild /p:LinkToolPath:crinkler.exe ...

It might also be possible to hack this into a vcxproj file but I didn't try.

When i tried to run the executable on higher versions than windows xp, it works. But when i try it on xp, the machine crashes with a irql_not_less_or_equal bsod. Any idea on how could i fix that?

I imagine this is a mistake, but this should be looked into.

Just clone this repo: https://github.com/stevefan1999-personal/crinkler-test, install Rust with rustup Crinkler with choco install crinkler and then run cargo run. It can compile, but it will get access violation on running.

Download choco.exe from here:

Try to compress using Crinkler.

Tool informs Unsupported file type when using on it.

It would be cool if crinkler could support the kkp format we use with rekkrunchy for 64k analysis. The format basically lists the source files, the symbols and then for each byte in the original executable the symbol located there, where in the source code it came from and the how many bytes it was stored as.

Hi,
I'm trying to build with Crinkler, but it seems to be stuck in an RVA forwarding loop. Is there a way to disable RVA forwardig with a command line switch? And if not, could anyone to point me to the place in source code where I can disable this myself?

This is what the output looks like:

1>LINK : warning LNK: Import 'CoCreateFreeThreadedMarshaler' from 'ole32' uses forwarded RVA. Replaced by 'CoCreateFreeThreadedMarshaler' from 'api-ms-win-core-com-l1-1-0'
1>
1>LINK : warning LNK: Import 'CoCreateFreeThreadedMarshaler' from 'api-ms-win-core-com-l1-1-0' uses forwarded RVA. Replaced by 'CoCreateFreeThreadedMarshaler' from 'ole32'
1>
1>LINK : warning LNK: Import 'CoCreateFreeThreadedMarshaler' from 'ole32' uses forwarded RVA. Replaced by 'CoCreateFreeThreadedMarshaler' from 'api-ms-win-core-com-l1-1-0'

1>LINK : warning LNK: Import 'CoCreateFreeThreadedMarshaler' from 'api-ms-win-core-com-l1-1-0' uses forwarded RVA. Replaced by 'CoCreateFreeThreadedMarshaler' from 'ole32'

and it just goes on forever like this in an endless loop

First it couldn't find the api-ms-win-core-com-l1-1-0.dll, but I copied it over from SysWOW64 and then it did that. I am on Visual Studio 2022.

I was trying to compress a win32 application with crinkler. I ran the following commands -
cl /c /O1 /GS- /Oi- /Gs9999 main.c
crinkler /TINYHEADER /SUBSYSTEM:WINDOWS main.obj kernel32.lib user32.lib gdi32.lib

It generates out.exe. But when I run the executable, it crashes with exception code c0000005. I ran the same executable in git bash where it showed segmentation fault. I googled the problem and found that it was trying to access some inaccessible memory region.

The program runs just fine when linked by link.exe

Hi,

I think there's a "practically never to expected" corner case how the arithmetic coding is ended:

Namely, I believe that if interval_size == 0x80000000 and interval_min == 0, then one should skip the ending altogether, as appending a 1 would get you halfway of the interval, but with interval_min == 0 and interval_size == 0x80000000, the half-way point is not included.

I think also interval_size == 0x80000000 and interval_min > 0 should be handled somehow differently.

I don't know how much thermal cooling of the universe would have to take place for this to occur in practice :) But I was reimplementing arithmetic coding and ran into this when my probabilities were getting messed up and got into the point that interval_size = 1, which got scaled to 0x80000000.

I was trying to compress a application using the following commands:

cl /c /O1 /GS- main.c
crinkler /nodefaultlib /entry:main /subsystem:console /out:tiktak.exe main.obj kernel32.lib user32.lib ucrt.lib libcmt.lib libucrt.lib libvcruntime.lib

Crinkler tries to link the libraries but crashes. Here are the dump + obj files.
dump-files.zip
Hope that helps finding the issue.

Whenever I try to use Crinkler I get the following error message:

C:\CODE\SML\EXAMPLE\4K.OBJ: error LNK: Unsupported file type

I am running an example from this repository that should work with no trouble.
Please tell me what I am doing wrong. Everything I am reading is telling me the following command should work:

cl /c /W4 /O1 /Os /GS- 4k.cpp

crinkler /ENTRY:EntryPoint  ^
         /SUBSYSTEM:windows ^
         /COMPMODE:SLOW     ^
         /HASHSIZE:100      ^
         /UNSAFEIMPORT      ^
         /OUT:4k.exe        ^
         4k.obj gdi32.lib kernel32.lib user32.lib winmm.lib

I am on a 64bit machine on Windows 10

Hi Rune,

Would you be interested in migrating to CMakeLists.txt instead of .vcxproj for builds? This would be the first step towards porting Crinkler to other platforms, or at least supporting other compilers than Microsoft (e.g. MinGW). Visual Studio users would not have to worry as:

• Visual Studio 2019 has a good support for CMake projects
• CMake supports nasm / yasm out of the box
• CMake could generate Visual Studio solution / project files if you really really need them.

Any thoughts? I can have a shot at this if you want.

running just crinkler.exe shows options but crinkler.exe /? does not. For example cmd /?.

I was going to use this linker to build a program with a custom stub, but I have noticed there's no STUB option, would it be possible to add one?
