These sorts of crashes are almost always caused by overwriting a memory
block you allocated.  It messes up the control data structures which
may not be noticed until a malloc many, many statements later which
happens to be in the same memory block size.  I would suggest a debug
malloc library, but I can't find mine right now :-(
