Isn't it just that the wrapper code (like the form files) can be very
large (very many lines of code in a single function or file) so the
compiler runs out of memory or takes a very long time to compute the
optimizations?

I changed to -O2 for the same reason in the Dorsal PETSc package
file. I think -O3 is ok for PETSc but I think of -O2 as optimize and
-O3 as try even harder.
