  No, you need the copy compiled with -g, but run without gdb.

  As soon as you get that register dump on the screen you
type  SYMIFY progname.exe
(replacing with the correct name).  It will read debug info from
the EXE and use it to modify the register dump right on your
screen.  That modified register dump is the starting point for
finding the problem  (post it here if it isn't obvious when you
see it).
