Can you try running under gdb itself, from the command line?  That might
help narrow things down.  Within gdb, just use "cd" to change directory
and "run arg1 arg2..." to run the program with specified arguments.

I don't believe that DDD does anything weird that GDB does not, but I am
willing to be proved wrong...
