Segfaults in free() are a fairly typical symptom of the application screwing up memory management, actually. freeing a block that was never malloced, freeing a block multiple times, and writing outside of the allocated boundaries could all cause this. If you're up to debugging it, electric-fence is a very useful tool; the way I use it is generally like this: myprog$ ./configure myprog$ make CFLAGS=-g myprog$ gdb myprog (gdb) set environment LD_PRELOAD /usr/lib/libefence.so (gdb) run and you'll generally get a segfault where the program actually messes up, rather than when the symptoms are seen later. There's a cost in both memory and runtime, but using LD_PRELOAD inside gdb makes this a lot less permanent. -- David Maze [EMAIL PROTECTED] http://people.debian.org/~dmaze/ "Theoretical politics is interesting.
