ElectricFence (devel/ElectricFence in the ports collection) detects most kinds of heap corruption, but not stack corruption. It will reliably abort the program on the exact instruction that first corrupts the heap (e.g. overruns a buffer), then you can use gdb on the core dump to analyze it further. After installing the port, run your program with "ef.sh". Tim
