Category: Core Group: MonetDB Common "candidate" >Status: Closed >Resolution: Fixed Priority: 5 Private: No Submitted By: zeuner (zeuner) Assigned to: Nobody/Anonymous (nobody) Summary: GDKupgradevarheap: copied area and allocated space mismatch Initial Comment: While for most variable-sized BATs the constraint H->heap.size == U->capacity << H->shift holds, it does not for those created by VIEWcreate_ (src/gdk/gdk_align.mx). As GDKupgradevarheap uses heap.size to decide what area to copy, and capacity to decide how much space to allocate, BATs created this way can cause writes to unallocated space when reaching this function. The attached patch eliminates this source of memory-related crashes by consistently using heap.size for both allocation and copying. ---------------------------------------------------------------------- >Comment By: Sjoerd Mullender (sjoerd) Date: 2010-02-03 14:00 Message: The essence of the patch was applied, and it seems to work well.
