Summary: doom3 segfaults sometimes in the _tnl_DrawElements code
Product: Mesa
Version: CVS
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Drivers/DRI/r200
AssignedTo: dri-devel@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
Even with tcl_mode=0 (on the radeon 9000pro) doom3 sometimes segfaults. It's
kinda hard to trigger, but it seems to happen always around the same places (one
place is at the end of the game, just some moments before approaching the
cyberdemon - just walking by there has a chance of around 20% to crash). There
are also some obvious rendering errors there (looks like misspecified polyons or
something like that, though it could just be z-fighting issues) which may be
related.
Program received signal SIGSEGV, Segmentation fault

v=0x11e57638 <Address 0x11e57638 out of bounds>) at main/api_loopback.c:280

#4 0x08156450 in ?? ()
(Now, with indices 666 it must just go wrong :-). Though "mode" and "type"
always seem to be the same.)
I'd suspect it's not a r200 driver specific problem, but I'd need days until I
would hit a crash with the software renderer...
