Looking quickly at the code the problem is that
LLL_MUTEX_LOCK (mutex)
fails to acquire the mutex. It can be a bug in atomic.h or a
bug in the
futexes implementation of the kernel.
It would be nice to have an strace of the problem to see the
futex
syscall before this assertion.
Also a small testcase of the problem would be really helpful
to debug
it.
