FpDebug has the advantage that it knows "fpc".

That is on top of what is specified by the dwarf info, fpdebug does look 
for other info.
Of course only, if it the dwarf info contains the producer = fpc.

ShortString (depending on dwarf version) is IIRC encoded as record. So 
any debugger will show this. But fpdebug looks for some details in how 
fpc writes various dwarf entries. And then detects it as shortstring. 
Though this works for known fpc versions only.
