I tried -fsanitize=thread and I got: ! ThreadSanitizer: CHECK failed: tsan_interceptors_posix.cpp:2107 "((thr->slot)) != (0)" (0x0, 0x0) (tid=1455863) but only with glibc 2.41. I am still unsure wether there is a race condition in PARI or not, however if there is, it is clear that 2.41 makes the issue much worse.
