Bug#391137: libgcc1 segfaults audacity
Package: libgcc1
Version: 1:4.1.1-15
Severity: important
I start audacity, then I press record, say something on the mic, and
when I press stop, audacity hangs. At first I thought it was an audacity
problem. So I ran gdb:
gdb /usr/bin/audacity
(gdb) r
And then I redid the process,
when I pressed stop, gdb replied:
Program received signal SIGSEGV, Segmentation fault.

I am not sure it is a libgcc1 problem, since it occurs only with
audacity, but since gdb accused the segfault on a gcc library I am
reporting this bug to this package.
