It would help more if you'd be able to reduce the problem from
"compile IDE with libgdb" to "compile this simple unit/program". Thus
could you please try to reduce the ide/fpregs.pp unit (which contains
the suspicious TVectorRegs record) so far that it can be compiled
standalone (no further dependencies), but still triggers the exception?
I'll be back.
This isn't quite what you've asked, but I can duplicate it with a
minimal program:
program test_fp_ide;
(* This is a specific test of the fp IDE interface to libgdb, which
fails *)
(* to compile on SPARC using fpc later than 2.4.x. MarkMLl.
*)
uses FPRegs;
// var vr: TVectorRegs;
begin
// WriteLn(SizeOf(vr));
end.

which takes us back to the same line
if (right.location.reference.offset mod alignmentrequirement<>0) or
with the implication that alignmentrequirement is unexpectedly zero.
Above is based on 2.6.2, running on SPARC Debian "Lenny". I'm omitting
details of the paths etc. pending confirmation that what I've got is of
some use.

I'm having problems reducing fpregs to a simple program, I'll post more
details once I've been able to look at it on the machine I've moved onto
for test purposes.
