[Bug c++/30891] New: poor diagnostic

[igodard at pacbell dot net]

The code:
int main() {
    int i = 0;
    namespace foo {
        int j = 0;
    }
    return 0;
    }
gets you:
~/ootbc/sim$ g++ foo.cc
foo.cc: In function 'int main()':
foo.cc:3: error: expected primary-expression before 'namespace'
foo.cc:3: error: expected `;' before 'namespace'


In contrast, Comeau gives:

        PR c++/30891
cp/
        * parser.c (cp_parser_statement): If 'namespace' is found, this
        only can be a namespace alias definition, so parse it now.
        (cp_parser_namespace_alias_definition): if we find an open brace
        instead of '=', then this is actually a misplaced namespace
        definition.
testsuite/
        * g++.dg/parse/namespace-definition.C: New.
