Why do you include windows.h in test.c?
I encountered following error.

/usr/include/w32api/processthreadsapi.h:165:11: Error: expected identifier or ‘(’ before numeric constant
  165 |     ULONG ControlMask;
      |           ^~~~~~~~~~~

Removing #include <windows.h> or adding
#undef ControlMask
is necessary to compile test.c without errors.

With that modification, your problem can not be reproducible
in my environment. The result is as follows.

not expecting a bug
