--- Comment #28 from Benjamin Kosnik <bkoz at gcc dot gnu.org> 2013-02-11 23:53:30 UTC ---

FWIW, I think the real fix here is to compile regex.cc with
-fimplicit-templates. I suspect that different things are being inlined on AIX
than on linux/ELF, there is an assumed implicit instantiation on AIX for this
symbol that is currently being supressed via -fno-implicit-templates.
