The fp IDE can drive libgdb to do straightforward debugging on x86

You're really picking your fights, aren't you? :) The textmode IDE is
probably the least maintained part of FPC currently, and Linux/SPARC
is not exactly the most used release either :)

Note that the code is correct: it's output the Hello World message
even though subsequently the debugger is confused.
d48656c = #13'Hel'. gdb on SPARC is trying to dereference the string
itself. I've fixed this in r13813 in trunk.
