--- Comment #4 from Casey Carter <Casey at Carter dot net> ---
There's some confusion here as a result of my inadequate description in the
original bug. The line `static_assert(S1<int>::f()); // Bogus error` is valid
but was not accepted and the line `static_assert(S2<int>::f()); // Bogus
non-error` is invalid but was not rejected. This should have been tagged both
"rejects-valid" and "accepts-invalid" (or better yet, I should have filed
separate issues instead of conflating the two).
As Andrew says, trunk now both accepts and rejects the cases it should here.
I'll simply close this since I don't think it provides any useful or unique
test case.
