and you forgot to run 'bt' or 'where' inside gdb.
Though one needs to be careful with threads. Signals aren't necessarily delivered to the thread that has sent the signal. So it's quite possible that some other thread has caused the segfault and what you see in gdb is just where the thread 12 happened to be at the moment. Are you sure that this is the only request you were running?
