Crashes inside the library function `free' usually mean that some
previous code overruns the end of an allocated buffer.  Look for a bug
along those lines, preferably by using some malloc-debugging tool,
such as YAMD or MSS.

Section 12.2 of the DJGPP FAQ list has more information about
interpreting crash messages like the one above, and some advice about
debugging such problems.

Probably not.
