A checking assert triggers upon the following invalid code since
GCC 11:
=== cut here ===
class { a (struct b;
} struct b
=== cut here ===
The problem is that during error recovery, we call
set_identifier_type_value_with_scope for B in the global namespace, and
the checking assert added via r11-7228-g8f93e1b892850b fails.
This patch relaxes that assert to not fail if we've seen a parser error
(it a generalization of another fix done to that checking assert via
r11-7266-g24bf79f1798ad1).

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
