This seems to be the case. I upgraded the compiler and tried again. The segfault didn't happen again. Note, this was not exactly the same situation as before because the git repository used for testing changed a bit since the first segfault.

I'll do some more repacking over the day and will report my observations.

It occurred on repacking a clone of git://git.kernel.org/pub/scm/git/git.git.
