[Boost-users] shared_array EXC_BAD_ACCESS

Hi there,

I'm attempting to use a shared_array as member of a class that I have. 
Something akin to the following:

     class UTFStringHolder
     {
                ...

        boost::shared_array<unsigned short> mStrBufferP;
     };

When UTFStringHolder is instantiated, I get an EXC_BAD_ACCESS and my 
stack trace shows that pthread_mutex_init is being called. Here's the 
complete stack trace:

#0	0x90012730 in _pthread_mutex_init

Any ideas/pointers? I'm using boost v.1.32. Thanks for any help as I'm 
going bonkers. :-P

Cheers,
