Run "mem" and make sure that you have *available* memory.  Note that
if you're using emm386 or qemm you must have available *expanded*
memory, else it uses XMS or extended.

Run under debug32 and watch the information on the top line.  The last
two numbers are memory used and memory remaining.  Swapping is
indicated by the third to last number, if it appears.

use "gcc -pg prog".  This will produce the gmon.out file.

Chances are, it's a bug.  The C++ classes are very old and I'm working
on porting the latest version.
