[Bug libstdc++/30280] New: SIGSEGV on operator==(valarray<bool>, bool)

[sebor at roguewave dot com]

The (strictly speaking ill-formed) program below successfully compiles with
gcc 4.1.0 but fails with a SIGSEGV at runtime. I think it should either fail
to compile or, if it compiles because of a gcc extension, it should also run
successfully to completion.

$ cat u.cpp && g++ u.cpp && ./a.out
#include <cassert>
#include <valarray>

int main ()
{
    std::valarray<bool> a (1);

    assert (a == false);
}

Segmentation Fault (core dumped)
