Description jerro.public 2013-03-20 18:54:37 CET 
A test case:

template Foo()
{
    void bar()
    {
        asm { "nop"; }
    }
}

mixin Foo!();

When building this with GDC 7907920a3ef0a26594c934, using gcc 4.8.0 RC1, I get:

Total time spent on bug:  Probably 120 seconds, idk. I step aside for a moment to serve myself dinner.
