--- Comment #10 from Richard Guenther <rguenth at gcc dot gnu.org> 2011-01-17 16:14:21 UTC --- The GNU linker made extern int abs_called; prevailing (it's a common, probably works with -fno-common?) instead of int abs_called = 0; thus I think this is a bug in the GNU linker (we remove the zero initializer I think, so maybe out LTO symtab we create is slightly odd).
