Hello!
As shown in the PR, ivar-invalid-type-1 ICEs in constructor_name_p,
due to accessor on NULL "type" argument.
The one-liner patch fixes the ICE by adding a guard that checks that
current_class_type is non-NULL before calling constructor_name_p.

* decl.c (grokdeclarator): Check that current_class_type is non-NULL
before calling constructor_name_p.
Patch was bootstrapped and regression tested on x86_64-pc-linux-gnu {,-m32}.
OK for mainline SVN?
Uros.
