(same result with -gstrict-dwarf).
So, this particular bug appears to be cleared at
dwarfutils-66 or greater. (confirmed at dwarfutils-70 as well)
(It does not seem to affect powerpc-apple-darwin8 which only has
dwarfutils-42,
but I can't speak for i686-apple-darwin-8)
Thanks. I'll now start to try and track down the orig_sym one.
Following Jakub Jelinek's advice (sorry I cannot find the post) I
have tried the
tests in gcc/testsuite/gcc.dg/guality/, but did not get any failure.
I'm currently regtesting 152114/i686-apple-darwin9 with my default
gstrict-dwarf patch and -g{no-,)gstrict-dwarf.
