Just checked, this example is working fine on Win64:

5         x := 5;
(gdb) step
6         writeln('x=',x);
(gdb) print x
$1 = 5
(gdb)

In any case, register indices and offsets are different matters and as 
it seems that DWARF indices are fine for stabs, I'd strongly vote for 
fixing x86_64 stabs info.

Cheers,
