testcase ICE because of the type mismatch.

On second thought, the implementation is simpler when NULL is not treated
specially. But then there is a slight majority of the uses in the
config directory that wants the old behaviour of get_unnamed_section,

How are you going to handle this? There's no meaningful syntax checking
without also creating modules. One could maybe create the modules in a

the current trunk compiler, it might be simply latent. The segfault

This is invalid code, since initialization expressions must be constants, and
the length of an assumed-length string argument is not a constant. Regardless,
we shouldn't be ICE'ing on it.
