I have scripts to fetch and rebase a list of 50+ repos.  I run this on
a 16-core AMD Windows Server 2008 R2 machine.  In about 1 out of 10
times, I get a "git fetch origin" that uses 100% of a core until
killed.

It just happened again a few minutes ago:

I tried strace, but it got a "Segmentation fault" on both the above
git processes.

What can I do to debug this?

Thanks.
