Still, I think the underlying issue warrants investigation.
I seem to recall that our gcc-4.2 with -O0 is known to be buggy -- certainly I just tripped over a panic in a third-party kernel module build using bsd.kmod.mk with -O0 that was fixed by compiling the object in question with -O. It is not terribly easy to search for, but my archives find at least http://lists.freebsd.org/pipermail/freebsd-current/2007-August/076028.html
I would try with -O1 and confirm that your issues go away, and not spend time on the core issue if it proves to be a gcc bug.
Unfortunately, we are stuck with an old gcc in base ... though I have yet to see if clang -O0 has issues with my module.
