Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Known to fail|4.0.1, 4.2.1 | --- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to Eric Gallager from comment #1) > With a really old gcc such as 4.2.1 the message is also bad: Because 4.2 doesn't support variadic templates, so it sees it as a basic syntax error.
