+2001-05-14 Mark Mitchell <mark@codesourcery.com>
- Workaround for p869:
- 1) grokdeclarator (around cp-decl.c:7462) is using popclass(1)
- uses popclass(1) to close the pushclass(3) done by
- build_push_scope; however, it's coming around another time and
- popping all the way out, which leads to the core dump when
- do_friend is called from global scope (do_friend uses
- current_class_name to figure out whose friendship it is
- bestowing.) Current workaround: if (friendp) don't allow
- popping all the way out. We still need to figure out how to
- make sure it only gets called the *right* time; we also need
