Problems "in the bowels" of malloc are invariably caused by memory
corruption, like double freeing of a pointer, overrunning of a buffer,
ignoring of OOM conditions, etc.  Given that the malloc in cygwin (to
say nothing of Doug Lea's malloc) goes through a fairly heavy workout
every day, I'd suspect the application before I'd suspect cygwin.
