Will have to re-check against another machine to be sure. -- You are receiving this mail because: You are watching all bug changes. |

I can only conclude that this test is contrived - and certainly looking at the generated trees, there's nothing we're really doing wrong here. This is testing GCC's ability to produce good code, not GDC's ability. -- You are receiving this mail because: You are watching all bug changes. |
