On the Linux kernel repository, doing "git shortlog v2.6.18.." works fine. "git shortlog v2.6.17.." works fine. "git shortlog v2.6.16.." also works fine. But "git shortlog v2.6.15.." dies with a segmentation fault. Trying "git log v2.6.15.. | git shortlog" also produces the same crash while "git log v2.6.16.. | git shortlog" works fine. The old perl version doesn't have any such issue with those test cases, not even with the whole kernel history.
