Summary: amaroK crashes mach64/no-DRI X server on ATI Rage LX Pro
Product: DRI
Version: XOrg CVS
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: libGL
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
I'm suffering from bug 4574, so DRI doesn't work and X falls back to software
rendering; this is annoying, but the Mach64 is bad enough at 3D that it's not a
killer.
But on XORG-6_8_99_900, firing up amaroK, clicking on the analyzer pane until a
graphical analyzer fires up, and then hitting `D' leads to the following crash:
Program received signal SIGSEGV, Segmentation fault.

Probable buffer overrun somewhere, I'd say. I can do more debugging if anyone
wants.
