Created attachment 596684 [details]
File: backtrace

Comment 2 Pádraig Brady 2012-07-06 23:08:19 UTC
That's a strange one.
If it is a bug I'd be inclined to think it's against glibc (2.14.90-24.fc16.7.x86_64)

There are similar failures in bug #746787 and bug #814235,
though they're in multithreaded programs.
uniq is not multithreaded, and I don't think implicit threads are created for it.

I presume this is not easily reproducible?

Comment 3 Ondrej Vasik 2012-07-07 17:15:24 UTC
Based on the backtrace it seems that this may be another flaw in downstream only multibyte i18n patch. Reporter, can you attach the reproducer files, if this issue is easily reproducible for you?

Comment 4 Olivier 2012-07-07 19:14:09 UTC
Hi Ondrej, Sorry I cannot reproduce this bug. It occured only once just after I logged in.

Comment 5 Ondrej Vasik 2012-12-13 08:32:46 UTC
Doing cleanup. Closing this one insufficient data, like Pádraig said, maybe glibc glitch. Because it is not reproducable, for the reporter, further analysis is probably impossible. Feel free to reopen the issue if you'll be able to reproduce this segfault somehow.
