           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

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.

Not an ice, as dmd itself does not hang. The compiled program does. Removed ice keyword.
