Hello,
Trying to do some stats using the Firefox git repository
(https://github.com/mozilla/gecko-dev), I found a bug
on git describe. The following command will segfault:
git describe --contains a9ff31aebd6dbda82a3c733a72eeeaa0b0525b96
Please note that the Firefox history is a pretty long and this commit
date is 2001.
I experience this issue with the git version, and Debian packages
(1.9.0-1 and 2.0~next.20140214-2)
As attachment, the backtrace. I removed about 87250 calls to the
name_rev function. I guess that is a potential source of problem.
Full is available here:
http://people.mozilla.org/~sledru/bt-git-on-ff.txt (21 MB)
I am available to test patches if needed.
Thanks,
Sylvestre
PS: I am not registered, please cc me.
