That's definitely a bug, and it doesn't look like any one that I know
about getting fixed in the upcoming 0.2.2.35.  The best place to
report bugs is trac.torproject.org.  The best way to diagnose a bug
like this is to use gdb to get a stack trace: if you still have the
core file and the binary that produced it, you can do that by running
"gdb path_to_tor path_to_core" where path_to_tor is replaced with the
path to the Tor binary, and path_to_core is replaced by the path to
the core file.  At that point, running "bt" should produce a useful
stack trace that shows where the error occurred.
