           Summary: static if (__traits(compiles)...) causes program to
                    hang
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody at puremagic.com
        ReportedBy: callumenator at gmail.com

DMD 2.062 Win32

import std.stdio, std.typecons;

void main()
{
    int ee = 0;
    static if (__traits(compiles, { Unique!int(&ee);}))
       auto e = Unique!int(&ee);
    writeln(e); // required to trigger
}

With the static if conditional (which passes) the writeln line causes the
program to hang indefinitely after printing the expected result. Remove the
static if conditional, and the program does not hang, behaves correctly.
