@mati865 do you understand what was python doing? If I have a command line to reproduce the problem I can investigate faster on my local machine.

Thanks!

I'm not an expert but these errors could be caused by miscompilation, library incompatibility or lack of free RAM.

EDIT: Hmm python2 wasn't downloaded or updated. Is Tea running latest python2 package?

Thank you.

Yes, Tea CI has latest Msys2 Python2 package pre-installed in docker image teaci/msys64 and teaci/msys32

I'll take some more time on this issue.

The below code reproduced a similar bug with Cygwin/Msys2 64bit on Wine, but works fine on Windows and 32bit Wine:

#include <unistd.h>
#include <stdlib.h>
#include <string.h>
#include <semaphore.h>
#include <pthread.h>


int
main(int argc, char *argv[])
{
    sem_t *p_sem = malloc(sizeof(sem_t));

    memset(p_sem, 0xcc, sizeof(sem_t)); /* trigger exception handling code in Cygwin sem_init()-->verifyable_object_isvalid() */
    sem_init(p_sem, 0, 1);

    return 0;
}
