            Bug ID: 278551
           Summary: pthread_join kills the process with a return code of
                    134
           Product: Base System
           Version: 14.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---

Console Output

Code:

void* kernel(void* par) {
    printf("kernel\n");
    return NULL;
}

int main(int argc, const char* const* args){
    pthread_t thread;
    pthread_create(
        &thread,
        NULL,
        kernel,
        NULL
    );

    pthread_join(thread, NULL);

    printf("FreeBSD RELEASE 14.0 doesn't reach here.\n");

    return 0;
}

Console Output:
kernel

The code above demonstrates that the call to pthread_join() with valid
parameters terminates the program with a return code of 134.

I have not tested this issue on bare metal so I don't know if my assigned
severity level is valid.

I'm using FreeBSD RELEASE 14.0 running on Proxmox with an 8 Core x86_64 Int=
el
XEON chip.

My libraries work fine on Windows, MacOS, Linux, and OpenBSD. pthread_join(=
) is
the only thing causing problems on FreeBSD thus far. Everything else seems =
to
be functional.
