digitalmars.D.bugs - bug 142 -- fixed but dstress still failing

Should that code even work? I'm no template guru (far from it), but I have no idea what should be happening. The template should generate a function called A, which in turn takes a parameter of type T, with T being "i"? I don't get it. L.

Honestly, I don't know. Templates aren't my forte at this point, but either the compiler is off or the dstress test is off, so _something_ is wrong. Later, Brad

No it shouldn't work. That's why the module name includes *nocompile*, I would think. The bug was that the compiler had an assertion failure when compiling that code (look at the summary), not that it didn't compile. I'm not sure why dstress lists it as "FAIL" though. I'd think it should be "XFAIL"... Thomas, can you shed any light on this?

Ok, so, um.. apologies for being obtuse. Is dmd still broken in your mind? If so, then either a new bug needs to be filed or bug 142 needs to be re-opened with details as to what's still wrong. Would you make the choice and perform the action? :) Thanks, Brad
