I'm running cygwin on baremetal on an Intel i5-750 (4 cores), with 7GB of RAM and with an up-to-date Windows 10.

At any given time during the RAM usage basically flat lines and there is still plenty of free memory left.

Thanks for tesing.

Thanks for the test case. I tried this test case, however,
I cannot reproduce the second problem, i.e. all 100 processes
exited normally.

To increase system load, I also tried:

#define UNICODE
#define _UNICODE

#include <process.h>
#include <stdio.h>

int main(int argc, char *argv[]) {
  wchar_t buf[1024];
  swprintf(buf, 1024, L"x86_64-w64-mingw32-gcc test.c -o %s", argv[1]);
  int ret = _wsystem(buf);
  if(ret != 0) printf("FOUND %d\n", ret);
}

and

#!/bin/sh
for i in $(seq 1 200); do ./a.exe $i & done

but, no error was found...

How many cpu cores and how much memory does your system have?
