I'm not sure if I'm doing something wrong, because other people should be seeing this too... Anyway, attached patch fixes the issue for me.

There is a reference in the patch file to #23524.

Oh, for the record, the build failure:

I was going to guess it was timemodule.c.

You need to "make distclean" or "hg purge" to clean up your repo. This seems to be some sort of gcc/configure issue. So far everyone else who has seen this has fixed it by cleaning their repo.

Indeed, make distclean fixes the problem.
