Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Core Group: MonetDB Common "candidate" Status: Open Resolution: None 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. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482468&aid=2936616&group_id=56967 ------------------------------------------------------------------------------ Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev _______________________________________________ Monetdb-bugs mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/monetdb-bugs
