If you compile your source files with the `-g' option, and don't strip
debugging symbols (don't use the `-s' option), you can type `symify
myprog.exe' while the crash dump is still on the screen, replacing
`myprog.exe' with the name of your program.

Incidentally, on this topic, why is it necessary to pass the name of
the executable image? The new stack trace contains the executable's
full path and filename; is this unreliable?
