I think this affects me - in my case, the SIGPIPE comes when I run 3dmark2000 or 3dmark06 in wine.
It only happens once in a while, but it's happened three times today.

Program received signal SIGPIPE, Broken pipe.
0xb7769430 in __kernel_vsyscall ()
(gdb) bt
#0 0xb7769430 in __kernel_vsyscall ()
#1 0xb754ea61 in writev () from /lib/tls/i686/cmov/libc.so.6
#2 0x080ad40e in ?? ()
#3 0x080acb5f in ?? ()
#4 0x080a84d6 in ?? ()

#6 0x080a8f71 in FlushIfCriticalOutputPending ()
#7 0x080723a5 in ?? ()
#8 0x08066d7a in _start ()

I've previously posted about this at
http://www.nvnews.net/vbulletin/showthread.php?p=2245689
and
http://<email address hidden>/msg00424.html
before I tried gdb; the stack trace from xorg.log looks different.

When I did 'cont' after the SIGPIPE, 3dmark2000 happily continues,
but I think without gdb there, the server aborts.

Oh, sorry, I should add that I've seen Xorg crash on 3d benchmarks on wine on
Ubuntu 10.04 32 bit with the 195.36.15 drivers that come with Ubuntu
and nvidia GT 220 and GT 240 cards, as well as on latest gentoo with gtx 295 cards.

Got a SIGPIPE again, this time while wineboot was running (just as 3dmark2000 was starting):

Program received signal SIGPIPE, Broken pipe.
0xb7769430 in __kernel_vsyscall ()
(gdb) bt
#0 0xb7769430 in __kernel_vsyscall ()
#1 0xb754ea61 in writev () from /lib/tls/i686/cmov/libc.so.6
#2 0x080ad40e in ?? ()
#3 0x080acb5f in ?? ()
#4 0x080a84d6 in ?? ()
#5 0x080a8f3f in FlushAllOutput ()
#6 0x0807230d in ?? ()
#7 0x08066d7a in _start ()

but this time I tried
   handle SIGPIPE pass
   cont
and X didn't crash. So perhaps not all SIGPIPEs are crashy.

[Dan Kegel (dank)]

This is now happening for me on *every* run of 3dmark2000.

That version is no more supported; please open a new bug report if the actual archive found version also has the same issue.
