Research direction
Start in llviewerobject.cpp at LLViewerObject::updateText() around line 6111, then trace getRenderPosition() and getPositionAgent() through LLHUDText::updateVisibility() and updateAll(). Use the BugSplat call stack to investigate the SIGSEGV and determine the object state that reaches the failing path; done means the reported crash no longer occurs.
