I start a second copy of X by running "X :1". Then, I run any program there, e.g. "DISPLAY=:1 xclock". After it starts, I kill the program with Ctrl-C.

Not sure if it's the same bug... If I run "xrandr" (as before, while I'm at :0, not :1), then the first time, it causes X to switch to vt8, with the :1 X running. If I run it again, X crashes: Backtrace: 0: X(xf86SigHandler+0x86) [0x80b7af6] 1: [0xffffe420] 2: /lib/libc.so.6(vsnprintf+0xb4) [0x432bac64] 3: X(LogVWrite+0x4e) [0x819f6ae] 4: X(LogVMessageVerb+0xed) [0x819f95d] 5: /usr/lib/xorg/modules/linux/libdrm.so [0xb7f1aebf] 6: /usr/lib/xorg/modules/linux/libdrm.so [0xb7f1d7b9] 7: /usr/lib/xorg/modules/linux/libdrm.so(drmOpen+0x4b) [0xb7f1dabb] 8: /usr/lib/xorg/modules/extensions/libglx.so [0xb7e86101] 9: /usr/lib/xorg/modules/extensions/libglx.so(__glXInitScreens+0xa2) [0xb7e63c92] 10: /usr/lib/xorg/modules/extensions/libglx.so(GlxExtensionInit+0x193) [0xb7e62d03] 11: X(InitExtensions+0xa2) [0x80eb252] 12: X(main+0x2dc) [0x806de8c] 13: /lib/libc.so.6(__libc_start_main+0xdf) [0x4327287f] 14: X(FontFileCompleteXLFD+0x91) [0x806d581] Fatal server error: Caught signal 11.

Please unmask and give 7.1 a try. There are a lot of crash fixes that have gone in since 7.0.
Please reopen when you reply.
Sorry for taking so long... I tried this with xorg-server-1.1.1 - and I still get the same crash.
Here's another crash... It might be related - also caused by glx. I started a second X server (so my main one doesn't crash :-/), and ran StarCraft, with Wine set to run programs in a 1000x800 window. This resulted in a crash: Backtrace: 0: X(xf86SigHandler+0x81) [0x80c3501] 1: [0xffffe420] 2: /usr/lib/xorg/modules/extensions/libGLcore.so(_mesa_resize_framebuffer+0x140) [0xb388a2c0] 3: /usr/lib/xorg/modules/extensions/libGLcore.so(xmesa_resize_buffers+0x4d) [0xb39b071d] 4: /usr/lib/xorg/modules/extensions/libGLcore.so(XMesaResizeBuffers+0x66) [0xb39ac466] 5: /usr/lib/xorg/modules/extensions/libGLcore.so [0xb39abdd0] 6: /usr/lib/xorg/modules/extensions/libglx.so [0xb7becbaa] 7: X(ResizeChildrenWinSize+0x197) [0x8074657] 8: X(miSetShape+0xda) [0x811ffda] 9: X [0x812b28a] 10: X [0x812b4a8] 11: X(Dispatch+0x18d) [0x8086add] 12: X(main+0x47e) [0x806e73e] 13: /lib/libc.so.6(__libc_start_main+0xdc) [0xb7cc887c] 14: X(FontFileCompleteXLFD+0xa5) [0x806da71]

You should try this one more against Xorg 7.2 when it's released. If it's still a problem, we'll move the issue upstream. If you want to give it a try early, just unmask Mesa 6.5.2 and xorg-server 1.1.99*.
Still the same with Xorg 7.2 Btw, this only happens if DRI is not working - if I start a second X server, or if DRI is not enabled in the kernel.
(In reply to comment #9) > Still the same with Xorg 7.2 > > Btw, this only happens if DRI is not working - if I start a second X server, or > if DRI is not enabled in the kernel. > Alright, please find/file a bug at https://bugs.freedesktop.org and post the link here when done. Thanks!
I filed the bug upstream a while ago, and it got fixed, but I forgot to post the link here. Here it is: https://bugs.freedesktop.org/show_bug.cgi?id=11340
