GDB does not work about ish HOT 7 CLOSED

I've never tried to run gdb so I'm not surprised this happens. In any case, gdb relies on ptrace which is totally unimplemented.

This seems to work now. It runs and seems to work fine on TestFlight build 45, but I haven't tried it any more than that.

It's not likely to work as well when you start trying to actually debug something though

Correct. Bad system call. dmesg crashed iSH once after that, but I cannot replicate it again.

34 missing syscall 136 When debugging hello world.

#include <stdio.h>
int main()
{
   printf("Hello, World!");
   return 0;
}

If saved as prog1.c

gcc  -Wall -Werror -ansi -pedantic-error
s -g prog1.c -o prog1.x
gdb prog1.x

Reading symbols from prog1.x...
(gdb) run

Should be fixed by #736, so closing this for now. Much of ptrace is still unimplemented, but you should be able to debug simple single-threaded programs now.

If you find something specific that's broken (hangs, strange errors) while debugging, feel free to make an issue for that.
