Without the quotes, I suppose :-)

And it is not well-formed if foo is not declared as a template yet,
but I agree that the message could be improved.

Bug reports are usually kept by developers in mailboxes or such, and
it's very good to have all the needed information in a single
message, rather than having to collect it from dozens of different
messages.  That's why I asked for a complete bug report.

Platform-dependent memory corruption can damage the symbol table,
which may lead to parse errors.

Thanks for re-posting it, anyway.

That's where bug reports belong; thanks :-)
