Description Dima Ryazanov 2007-06-22 17:47:39 UTC 
If I start a second X server or if DRI is not available for some other reason, X crashes when the last client exits.
An easy way to reproduce:

X :1
DISPLAY=:1 xset q

Backtrace:
#0  0xb7c14342 in DRIOpenConnection (pScreen=0x820dad8, hSAREA=0xbfb4fae8,
    busIdString=0xbfb4fae0) at dri.c:663
#1  0xb7c7a815 in __glXDRIscreenProbe (pScreen=0x820dad8) at glxdri.c:904
#2  0xb7c467ad in __glXInitScreens () at glxscreens.c:341
#3  0xb7c45785 in GlxExtensionInit () at glxext.c:350
#4  0x080eee02 in InitExtensions (argc=3, argv=0xbfb4fc74)
    at ../../../mi/miinitext.c:774
#5  0x0807013f in main (argc=3, argv=0xbfb4fc74, envp=0x50) at main.c:379

It crashes when trying to access pDRIPriv->pDriverInfo->busIdString.

Wow, that was quick. Thanks!

This bug annoyed me for years... But I never bothered to report it, until now :-/
