--- Comment #1 from Dimitry Andric <dim at FreeBSD.org> ---
Any idea how to reproduce this? It appears that mutex::lock() just calls
pthread_mutex_lock() and it fails somehow:

00000000000b5380 <std::__1::mutex::lock()@@Base>:
   b5380:       55                      push   %rbp
   b5381:       48 89 e5                mov    %rsp,%rbp
   b5384:       e8 67 e7 00 00          callq  c3af0 <pthread_mutex_lock at plt>
   b5389:       85 c0                   test   %eax,%eax
   b538b:       75 02                   jne    b538f
<std::__1::mutex::lock()@@Base+0xf>
   b538d:       5d                      pop    %rbp
   b538e:       c3                      retq
   b538f:       48 8d 35 e8 a0 f8 ff    lea    -0x75f18(%rip),%rsi        #
3f47e <typeinfo name for std::bad_any_cast@@Base-0x8df>
   b5396:       89 c7                   mov    %eax,%edi
   b5398:       e8 d3 d2 00 00          callq  c2670
<std::__1::__throw_system_error(int, char const*)@plt>

So in frame 5, can you print the value of 'ec' ? pthread_mutex_lock(3) says:

ERRORS
     The pthread_mutex_lock() function will fail if:

     [EINVAL]            The value specified by mutex is invalid.

     [EDEADLK]           A deadlock would occur if the thread blocked waiting
                         for mutex.

     [EOWNERDEAD]        The argument mutex points to a robust mutex and the
                         process containing the previous owning thread
                         terminated while holding the mutex lock.  The lock
                         was granted to the caller and it is up to the new
                         owner to make the state consistent.

     [ENOTRECOVERABLE]   The state protected by the mutex is not recoverable.

I wonder what the actual error is...
