Hey, the attached patch prevents inserting the same pointer into a ptr_set. The result of inserting it a second time is that on the second pointer delete is called which in the end invalidates both the data behind the pointer and also the already existing entry in the ptr_set.
The patch is a 3-6 version of http://cgit.freedesktop.org/libreoffice/core/commit/?id=34638df69902a2251e8c23833b62c005a754fd5d Regards, Markus
