Make use of electricfence (libefence) for tracking memory allocation errors. In debian this can be enabled on the fly by setting an LD_PRELOAD variable, like so:
LD_PRELOAD=libefence.so.0.0 your-buggy-programme

+Note: When using gdb(1) to debug a threaded program, gdb(1) catches two signals ([SIGPWR] & [SIGXCPU]) which are used internally by pthreads on Linux. Use
+ (gdb) handle SIGPWR pass nostop noprint
+ (gdb) handle SIGXCPU pass nostop noprint
+to stop gdb halting on receiving these signals.
