Public bug reported:
Binary package hint: msort
The msort utility crashes when I try to sort a large webserver logfile
by date/time. This used to work on Gutsy, but it's broken in Hardy. When
I run my logfile proecessing script, I get the following dump:
*** glibc detected *** msort: munmap_chunk(): invalid pointer: 0xbf87fab4 ***
