Core dumps are almost always just called "core". Run the program "file" on mydump.dump and see if it recognises it as a core dump. Maybe the program has it's own crash parachute and this file is just some debugging information?

As kskkumar explained, core dumps are files usually named only "core". With gdb you first load the file, then you load the core dump; or from the command line: gdb yourprogram core .

Remember to do a "man gdb" or go the the gnu.org website for documentation.

Also, the "ulimit" command allows to specify the core dump size limit, if my memory doesn't fail me it's "ulimit -c unlimited" for example. Again, check its manual.
