Wow, I had completely forgotten about the time I spent puzzled over this
behaviour in 2013.

I'm guessing that just the existence of this as a bug report for 'condition
variables static linking' is sufficient documentation for the rare time it
happens for people. As such I'll note that my unpleasant fix was to include
this in a header:

void pthread_cond_bug() {
        pthread_cond_signal((pthread_cond_t *) nullptr);
        pthread_cond_init((pthread_cond_t *) nullptr,
                          (const pthread_condattr_t *) nullptr);
        pthread_cond_destroy((pthread_cond_t *) nullptr);
        pthread_cond_timedwait((pthread_cond_t *) nullptr, (pthread_mutex_t *)
                               nullptr, (const struct timespec *) nullptr);
        pthread_cond_wait((pthread_cond_t *) nullptr, (pthread_mutex_t *)
(nullptr);
}

without actually ever calling it; iirc it links in the functions as a result.
