Okay. My original reduction was okay but I also added additional examples that
yielded the same assertion failure (obviously via different route!). The
function-call case following is the one that causes the failure in
non-dependent use of boost.foreach on the latest 4.6 HEAD. It compiles okay on
my 4.6 build from last week (prior to 170488).
if (from_int<int> x = via_function(7))
;
The constructor cases below have failed for a much longer time (though are okay
in 4.5).
if (empty<int> x = empty<int>())
;
if (from_int<int> x = from_int<int>(7))
;
So the only recent regression is the function-call case. But all cases are all
still legitimate 4.5 -> 4.6 regressions.
Before rev 170488 (25th Feb) the function-call case compiled.
I don't know when the constructor cases stopped working -- I went quite a way
back and they still failed.
