OS X Bounds Checking

Another useful GDB-ism, if you’re on OSX/Darwin (the excellence of which, as a development platform, should be fertile ground for future posts):

(gdb) define guard
> set env DYLD_FORCE_FLAT_NAMESPACE 1
> set env DYLD_INSERT_LIBRARIES /usr/lib/libgmalloc.B.dylib
> end

Stick this in your “.gdbinit”; type “guard” before running your program, and you get bounds-checking malloc.
