Can you run main.exe directly?

Of course.

Can you copy main.exe somewhere I can download it from?

testdlv.zip

main.exe in the zip is the exe generated by go build main.go. main-modified.exe is the result of go run addres.go.

The original content of main.exe is irrelevant actually. It can be any exe generated by go build.

That message is happening because debug/pe.NewFile returns an error, so this problem should be reported to https://github.com/golang/go/issues/.
However modified-main.exe does look malformed, the PointerToSymbolTable and NumberOfSymbol entries of the file header are unchanged, even though something has been added to the file, so debug/pe can't find the string table. Gnu objdump can't parse the executable file either.

Reported.
