[tor-dev] [Win32] crash in test/bench.exe

[Gisle Vanem <gisle.vanem@xxxxxxxxx>]

There is a crash in bench.exe. Running 'cdb -c g bench.exe':

ntdll!RtlpWaitOnCriticalSection+0x6b:

Seems bench.c uses some mutex which is not initialised
with 'tor_mutex_init()'. I fail to see which that should
be.

FYI.
'&m->mutex' is 0 (= eax). But adding:
  tor_assert(&m->mutex);
  tor_assert(&m->mutex.OwningThread);
to 'tor_mutex_acquire()' didn't help reveal the problem.
