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.

I'm currently regtesting 152114/i686-apple-darwin9 with my default  
gstrict-dwarf patch and -g{no-,)gstrict-dwarf.
