          Issue ID: 14587
           Summary: DMD 2.067.1 generating crashing binary on OSX
           Product: D
           Version: unspecified
          Hardware: x86_64

(reporting as an issue - suggested by John Colvin)

I'm consistently getting "Segmentation fault: 11" (dmd 2.067.1, OSX) on the
code below.

I can't figure out where things are going wrong, because any attempt I make to
debug via extra print statements causes the program to run successfully. Same
if I try to compile with "-gc" ... it suddenly starts working, so I can't debug
with gdb. And the code similarly seems to work fine with ldc2.

Many thanks in advance!

import std.stdio;

enum Suit {
    HEARTS, DIAMONDS, CLUBS, SPADES
}

enum Value {
    ACE = 1, TWO, THREE, FOUR, FIVE, SIX, SEVEN, EIGHT, NINE, TEN, 
JACK, QUEEN, KING
}

struct Card {
    Value value;
    Suit suit;
}

void printCard(in Card card) {
    final switch(card.value) {
        case Value.ACE:
            write("A");
            break;
        case Value.TWO, Value.THREE, Value.FOUR, Value.FIVE, Value.SIX, 
Value.SEVEN, Value.EIGHT, Value.NINE, Value.TEN:
            writef("%d", card.value);
            break;
