Hi, Thanks for the replies and suggestions.
I think I might not have explained the issue as well as I thought, so I'll try again. QThread::currentThread does return a value with static type QThread*. However, it might not point to a QThread instance, but an instance of a subclass of QThread. The problem is that OpenThreads assumes that the return value can be cast to a pointer to a specific subclass of QThread that OpenThreads defines, QtThreadPrivateData, like this: Code: QtThreadPrivateData* pd = static_cast<QtThreadPrivateData*>(QThread::currentThread()); This is a problem because if the current thread is a different subclass of QThread, this cast is invalid so when the new pointer (pd) is used, it causes a seg fault or random behavior. We have observed in our application that this does in fact sometimes occur. Specifically, QThread::currentThread can return a QAdoptedThread*, which is legal since QAdoptedThread is a subclass of QThread. I hope this clarifies things. Thank you!
