If I debug a 32 bit app (on w32) compiled with trunk (maybe 3 weeks

Then I get the high and low 32bits swapped. so instead of a value of

Does anyone know if thats gdb, or something on how fpc wrote the
dwarf info (-gw) ?
That sounds like a bug in that particular gdb version. It at least
works fine for me with gdb 7.0.1 under Linux/i386:
$ cat tt3.pp
var
q: qword;
begin
q:=139784704;
end.
$ ppn12 -gw tt3.pp
