Summary: SIGSEGV in _radeon_bo_unref
Product: Mesa
Version: git
Platform: x86 (IA32)
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Drivers/DRI/r200
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: david.ro...@mcgill.ca
I occasionally crash in the sauerbrauten game (even after the fix in bug
#25355); the problem seems to be game-map related. I'm following the
git/master.
I see the following on the console:
*********************************WARN_ONCE*********************************
File radeon_dma.c function radeonReleaseDmaRegions line 340
Leaking dma buffer object!
***************************************************************************
>From the backtrace it's clear that radeon_bo_unref is being passed a NULL
pointer. My bet is that the culprit is radeonReleaseDmaRegions' calculation of
bo (like in bug 25355).
Here's the backtrace:
Program terminated with signal 11, Segmentation fault.
