I managed to reproduce this problem reliably. It has to do with the Fortran front end (indirectly) invoking varpool_finalize_decl much later than the C front ends do. Without the decls being finalized, the IPA pass doesn't get to see them and they don't get lowered.

I talked to Richi about this ordering problem on IRC, and changing the
generic ordering of decls vs compilation unit finalization appears to run
into problems with C++ and Java and their aliases.  An acceptable solution
appears to be to hack the Fortran front end to do it by hand.

Hmm, I wanted to get decl finalization out of wrapup_global_decls for a while but never got around it. What are those problems with aliases?
