Hi,
Using cygwin 3.6.0-0.66.gc77a5689f7bd I was indeed unable to reproduce the issue.
However I'm getting a related but slightly different issue now, where a subprocess randomly (but quite reliably over the whole compilation process) fails with make -j (works fine with -j1 once again)
Luckily i was able to make a really small test-case this time:
Using MinGW 11.4.0 with the following test.c file:
#define UNICODE
#define _UNICODE
#include <process.h>
#include <stdio.h>
int main() {
int ret = _wsystem(L"x86_64-w64-mingw32-gcc -dumpversion");
if(ret != 0) printf("FOUND %d\n", ret);
}
compile using: x86_64_w64-mingw32-gcc ./test.c
and run using: for i in $(seq 1 100) ; do ./a & done
You should now be able to see at least one FOUND line among the output.
This exact behaviour happens to me everytime I try to compile the OCaml compiler, where a gcc subprocess fails inexplicably.
We've been getting this kind of error once in a while over the years (locally and in CI) but it was never reproducible to this point and it was usually fine if we restarted the compilation.
Kind regards,

I can confirm this fixes the issue for me, thank you!
