Help: corrupted stack

["Andrew or Yssa DeWoody" <dewoody at athens dot net>]

I'm running a  C program at the DOS prompt that was compiled by gcc.  The program is using the  Kutta-Merson algorithm to integrate big set of differential equations forward in time.  The program (new3.c) compiles without warnings or errors.  The program appears to run fine (meaning the output to the screen is normal), but at the termination of the program I get the message displayed below and the output files created by the program are all mess up.  I get the same message if I run the program in bash.

Is this a memory problem?  Any suggestions on how to fix it?

 

Thanks,
