After talking with @kmcallister on IRC, turns out this also produced an error for him:

#include <assert.h>
#include <pthread.h>
#include <stdio.h>

int main() {
    pthread_mutex_t lock;

    assert(pthread_mutex_init(&lock, NULL) == 0);
    assert(pthread_mutex_trylock(&lock) == 0);
    assert(pthread_mutex_unlock(&lock) == 0);
    assert(pthread_mutex_destroy(&lock) == 0);
}

I think this may be a local bug rather than a bug in Rust, so closing.

Fixed by apt-get dist-upgrade. This is what I get for running Debian unstable...

I had the same issue. Upgrading the package libc6 from 2.19-12 to 2.19-13 fixed this issue.
