------- Additional comments from [EMAIL PROTECTED] Mon Feb 13 03:06:21 -0800 2006 ------- attached patch implements a more comprehensive fix, which only touches SVX, but not SC (or the other applications). Basic change compared to the previous patch is that now SvxShape::release is overridden, making the "release the last reference, and delete |this|" an atomic operation, guarded by the SolarMutex. Additionally, methods of the SvxShape which could be called bypassing UNO (such as the |dispose| call from SdrObject::~SdrObject, or SvxShape::Notify), but create a reference on the SvxShape itself, have been protected against duplicate deletion. (That is, if thread A blocks in SvxShape::release, with the ref count already dropped to 0, and thread B enters one of those methods, and creates a temporary reference to the SvxShape instance, then this would result in duplicate "delete this" calls, and thus a crash.) This works with all integration tests from "forms", which make extensive use of shapes in both Calc and Writer. Not yet verified against various past bugs in this area ... --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
