TauLabs/TauLabs#1594 details a simple reproducible RawHID segfault. The stack trace shows that RawHID::close is being call but there was never a call to RawHID::open so the read and write threads are never created -> RawHIDWriteThread::stop tries to dereference m_writeThread which is a null pointer..
Backtrace for the main thread which encounters the segfault
