- That's not likely to be a problem with malloc. Most likely something
- else in your code is broken someplace. From the behavior of the GNU malloc,
- it sounds like you're pasting something in your memory, either with a wild
- pointer, or you're double-freeing something, or freeing something that you
- never malloced in the first place...
