problem with explicit template function specification

It's in 5.2, [expr.post]/1

# postfix­expression:
#                    ...
#                    postfix­expression . template-opt id­expression

Usually, you leave the optional template out. As Alexandre points out,
you only need to have it if the postfix-expression depends on the
template parameter (and the id-expression is meant as a template-id),
which was not the case in your example. So it still is a bug that gcc
requires it.
