Summary: Crash (backtrace included) when playing maniadrive
Product: Mesa
Version: CVS
Platform: Other
URL: http://maniadrive.raydium.org/
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: Drivers/DRI/i915
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
When trying to play maniadrive on any of the i915 driver using 865 intel
machines at work, it crashes. Both when using Fedora 8 and when using Fedora 8
+ the mesa 7.1 snapshot from Fedora development. It worked just fine around
Fedora-8 release candidate 1 so this is caused by a pretty recent change.
Maniadrive is a bit hard to build I'm afraid, but if you have a Fedora machine
its just a yum install away, otherwise its available here:
http://maniadrive.raydium.org/
When run under the debugger this is where it crashes:
#0 0x01ac1744 in triangle_twoside (ctx=0x8f89078, e0=6, e1=9, e2=8)
at ../../../../../src/mesa/tnl_dd/t_dd_tritmp.h:202
202 GLfloat (*vbcolor)[4] = VB->ColorPtr[1]->data;
(gdb) p VB->ColorPtr
$9 = {0x8fc9d4c, 0x0}
(gdb)
Notice how the second pointer if the 2 big pointer array VB->ColorPtr is NULL,
explaining the crash.
I'll attach a full backtrace, and I'm more then happy to do some scratch builds
/ do printing of some specific variables in other stack frames.
