Subj : pthread and C++

Im sorry if this has been answered recently and I failed to see the
posting.

Is it not possible to access C++ object public members from pthreads?

Im doing the following and getting exceptions:

Using a global pointer to a dynamically allocated C++ object, i am
passing the pointer to pthread_create.

Within the body of the thread function, I cast the argument to my
class type like this:

void* threadServiceInput( void* arg )
{
	// cast arg to my object pointer
	myClassT* ptr = reinterpret_cast<myClassT*>( arg );

But anything i access via ptr-> pops an exception.

I don't recall having this problem before with POD structs, so for
now, my best guess is an incompatibility with C++ types.

Please advise,
Charles
