http://d.puremagic.com/issues/show_bug.cgi?id=5580 --- Comment #4 from David Simcha dsim...@yahoo.com 2011-02-15 06:30:28 PST --- My gut feeling is that this is related to Bug 5581, as both invoke calls to memcmp() according to my reading of the disassembly and tracking down of the function calls in the runtime. However, 5581 seems to be reproducible everywhere. If you can't reproduce this, I suggest fixing 5581 first. Once 5581 is fixed, I'll retest this bug on a machine that I was able to reproduce it on and hopefully it will be fixed, too. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

One thing you can try on the failing machines is to copy switch_.d into a local directory, compile it with the test case, and verify the failure. Then add some print statements to switch_.d to try and see where it goes wrong. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

http://d.puremagic.com/issues/show_bug.cgi?id=5580 --- Comment #6 from David Simcha dsim...@yahoo.com 2011-02-15 18:10:56 PST --- Unfortunately this appears to be a Heisenbug. When I put print statements in to figure out what's going on and call the switch statement function manually, it starts working. However, the one hint I did get from mucking around in switch_.d is that replacing the memcmp() call with a manual for loop and recompiling druntime solves the problem. Not sure if this is due to the Heisenbug nature of this thing or if it indicates that the memcmp() call is the culprit. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---
