I customized zsim, and I'm having problems running multiprogram applications. With the original zsim, I dont have such a problem.
My program crashes when it synchronizes in the barrier, specifically when doing the futex syscall (in barrier.h):
int futex_res = syscall(SYS_futex, &threadList[tid].futexWord, FUTEX_WAIT, 1 /*a racing thread waking us up will change value to 0, and we won't block*/, nullptr, nullptr, 0);
The error message is attached below. Any idea on why the syscall is crashing?
Hello,

Thank you very much
