OK. I can successfully run following code (with assertion failure, of course):

import std.stdio;
void main()
{
    auto file = File("testcase.d","r");
    foreach (ulong i, string line; lines(file))
        assert(false);
        // Segmentation fault (core dumped)
    file.close();
}

without any switches using githead. The fact that you are facing bug my be
because it is already fixed in head. Can you test master branch? If there are
no objections, I will close issue as WORKSFORME.
