BASIC DETAILS
=============
I'm experiencing intermittent checkout crashes with svn 1.8.9 on FreeBSD
that
aren't easily reproduced. I've included the latest three crash logs (the
earlier crashes were similar to the first two I've included -- seen in
gdb to
occur at the same point -- but I didn't save the core files for those).
The checkout will usually run for minutes at a time before the crashes
occur, displaying a lengthy list of successfully added files ("A ...")
before
segfaulting somewhere through. On some runs, I've managed to checkout
everything without incident. There appears to be no rhyme or reason to
which
particular file fetch causes the crash.
If there's anything I can do to help a fix along, please let me know.

COMMAND LINE
============
