The test case below fails assert on all versions of g++ from 2.95.3 through 
4.0 (20040919 snapshot), on all platforms.

--- cut ---
#include <valarray>
#include <cassert>

int main()
{
    std::valarray<double> v(1);
    std::valarray<double> r;

    r = v;
    assert(r.size() == 1);
    return 0;
}
--- cut ---

$ /usr/local/gcc-4.0/bin/g++ -g exp2.cpp
$ ./a.out
a.out: exp2.cpp:14: int main(): Assertion `r.size() == 1' failed.
