Hi Ariel,

Yes, due to GC undeterministic cycles, the potential risk exists in many places, but because of the pinning performance penalty, better pinning only the functions that you see that fails in your application. The QF 1.12.4 already has the major required pinned objects, but my personal experience showed me that when the application has a higher volume of messages to process, some methods that take a relatively long time to run, like toString and addGroup, must all be pinned to avoid this error.

Following is toString fixed code:

String* ToString()
{ QF_STACK_TRY
	QuickFix::Message __pin * pThis = this;
	return new String( pThis->unmanaged().toString().c_str() );
QF_STACK_CATCH
}
