[Bug c++/23705] New: [4.0/4.1 Regression] zone allocator broken

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

I am filing this bug to track the process of this regression.
It was caused by the following patch:

        PR c++/21687
        * parser.c (cp_parser_class_specifier): Push/pop GC contexts
        around functions in local classes.

The reason why this fails is because the zone allocator does not have ggc_{push,pop}_context.
All push/pop context's were removed in 4.0.0 for speed and they were not needed any more.
This is also a regression on the release branch from a previous release from that branch which is really 
bad news.
