Why is this a regression? Previous GCC releases did not even support variadic
templates.

Confirmed. the regression is an ICE for error recovery.

Mark, this is really only an error recovery regression. Can you relook at the
current priority?
Thanks,

What happens in C++0x mode? The error about variadic templates not being part
of ISO C++ would presumably not occur in that mode.

Correct but C++0x mode was not in 4.2 so only the normal gnuC++98 mode issue of
an error recovery can be a regression.

------- Comment #6 from mmitchel at gcc dot gnu dot org 2007-12-02 21:25 -------
I disagree.
If we bring out a new feature in the compiler, then that new feature should be
robust. We do not want to tell users that one of the great new things about
GCC 4.3 is C++ 200x support, only to have them find that it tends to crash when
they make a mistake in their code.
