take a look at http://rr-project.org/
with it, you can record a run of your program
then play it back, deterministically, in gdb.
Once you identify the object addresses giving you trouble,
you can set watchpoints on them, replay,
and catch the origins of the eventual segfault
I havent used it in earnest yet,
but its at the top of my must-learn-tools list.
Id love to see valgrind running one of these recorded sessions,
it would yield a tremendous amount of info for use in
further gdb replay-sessions
