As far as I know this is the full executable as it was before rpmbuild did 
call strip. It puts the stripped one in the normal rpm and the original 
one in the debuginfo rpm.

There exists no debugger that can process the .dbg files FPC generates, 
and gdb cannot read debug info from a file in general. The /usr/lib/debug 
means gdb simply opens a different executable.
