Hi!
http://gcc.gnu.org/ml/gcc-patches/2009-11/msg01059.html
broke completely Obj-C++. The problem is the new set_underlying_type
call in build_self_reference, which creates a new type variant.
The ObjC FE apparently isn't prepared to see such a type variant in
objc_build_struct, expects that all type variants have already
TYPE_OBJC_INFO initialized.
The following patch fixes it, bootstrapped/regtested on x86_64-linux, fixes
all the recent obj-c++ regressions.

* objc-act.c (objc_build_struct): INIT_TYPE_OBJC_INFO for
type variants that don't have it initialized yet.

OK, seems reasonable. If ObjC folk want to do something else, they can.
