[Bug 328035] Re: *** glibc detected *** free(): invalid next size (fast) for xf86Wakeup() call

[Steve Langasek]

Was going to bisect, then noticed that the first xserver-xorg-video-
intel version where I started seeing the problem had a changelog entry
describing a single fix related to switching video output - which is
precisely what appears to trigger the bug for me.  Have downgraded to
2:2.6.1-1ubuntu1, and so far X is stable for me again, in the face of
being exercised with lid open/close, suspend/resume, toggling video
output, etc.

No clue why that small patch from -1ubuntu2 is triggering heap
corruption - clearly the corruption is happening in some other part of
the code.  But I'm about 98% certain that this is the change that
introduced the problem.  I'll continue to run with this version for the
time being and try to trigger the crash in the usual ways (you know,
suspend/resume, sneezing, etc).

** Changed in: xserver-xorg-video-intel (Ubuntu Jaunty)
Sourcepackagename: xorg-server => xserver-xorg-video-intel
