[Bug 20335] New: Uninitialised memory reference in X11DRV_DIB_SetImageBits()
http://bugs.winehq.org/show_bug.cgi?id=20335 Summary: Uninitialised memory reference in X11DRV_DIB_SetImageBits() Product: Wine Version: 1.1.31 Platform: PC OS/Version: Linux Status: NEW Keywords: download Severity: normal Priority: P2 Component: winex11.drv AssignedTo: wine-bugs(a)winehq.org ReportedBy: dank(a)kegel.com I think this is one of the first valgrind warnings I ever ran into in wine, and it's still here. Nowadays Wine gives better warnings, so it's a little easier to see where these are coming from. Running chromium's base_unittests.exe (and probably lots of other apps) in valgrind yields this warning: Conditional jump or move depends on uninitialised value(s) at XcursorImageHash (xlib.c:294) by XcursorNoticePutBitmap (xlib.c:365) by _XNoticePutBitmap (CrGlCur.c:202) by XPutImage (PutImage.c:1042) by X11DRV_DIB_SetImageBits (dib.c:3670) by X11DRV_SetDIBits (dib.c:4040) by SetDIBits (dib.c:361) ... Uninitialised value was created by a client request at RtlAllocateHeap (heap.c:187) by X11DRV_DIB_SetImageBits (dib.c:3543) by X11DRV_SetDIBits (dib.c:4040) by SetDIBits (dib.c:361) ... Presumably adding HEAP_ZERO_MEMORY to the allocation at dib.c:3543 would do the job, but maybe there's a smarter way. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
