[Bug 710755] Re: compiz crashed with SIGSEGV in _mesa_generate_mipmap()
Same here; Compiz crashed on alt-tab, and my mouse worked but my
keyboard became useless. (This might be an artifact of Unity or
something?) Manually running Metacity let me log in to post this.
I don't believe Launchpad uploaded my crash report since I marked it as
a dupe, but I can send it out of /var/crash if anyone wants it. The
exact offending instruction was a bit different:
SegvAnalysis:
Segfault happened at: 0x7fc6f8779f4b: movzbl (%r9),%r10d
PC (0x7fc6f8779f4b) ok
source "(%r9)" (0x00000000) not located in a known VMA region (needed readable region)!
destination "%r10d" ok
