   I get the attached output.  Why is this mmx stuff showing up?  And
   what are the bits about bash?

GDB exec's a shell to setup your environment properly then execute the
program to be debugged.  In this way GDB's environemnt doesn't need
to be altered among other things.

The mmx bits are just some of the search path postfixes glibc uses to
find optimized versions of libraries appropriate for the kind of cpu
execution takes place on.
