This is _not_ necessarily a crash. If this is OS X, this signal is used by
the garbage collector to detect when memory is written to, marking it for
inspection later on. What I meant is to really run a program, no GDB
involved, and see whether you experience this crash. If you use GDB then you
have to tell it to ignore this signal (handle EXC_BAD_ACCESS pass nostop
noprint or something like that)
