          Issue ID: 20441
           Summary: Wrong code with -O -fPIC and string literal.ptr
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: critical
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: clugdbug at yahoo.com.au

This reduced test case tested with 2.086, but original bug was found with 2.089
and 2.078.

Assert fails if compiled with -O -fPIC. Passes if compiled without -O.

const(char)* moo(const (char) *s)
{
    return s;
}

void main ()
{
    const(char) *x = "abc".ptr;
    assert( moo(x) - x == 0 );
}
