It's not that useful to us, but the EIPs (instruction pointers) are
useful to DJGPP's symify debugging tool. Provided you built
your program with debugging turned on (check the FAQ), do this:
symify c:\codename.exe
and look at what it gives. This may clue you in on what function
is misbehaving. The output from symify would help us greatly.

1. Open a Windows 95, 98, or NT command prompt
(Start > Run... then type command and press enter)
2. Run your program.
3. Run symify on the error messages.
4. Use the Windows editing tools to grab the screen:
  1. Right click MS-DOS Prompt in the taskbar.
  2. Choose Edit > Mark
  3. Drag across the error output, especially the traceback.
  4. Choose Edit > Copy
5. Paste the traceback into your news reader.
