Even though they are compiled, has anyone opened such a file with a hex editor
and poked around looking for human readable text? Dumping it as ASCII will
almost always give gibberish because of odd compilation artifacts. But a hex
editor in a debugger will translate text information into ASCII nicely. There
are lots of tools to do this on GNU/Linux platforms but I don't know about
Macintosh.
Also, is the dump you included that of your little test program or of the
results it obtained when used? The latter would be more interesting.
Happy Hacking,
