David:
I generally tend to ignore dmd bugs and just workaround them, I don't have the time to track down every stuipid bug from a ~8k codebase.
I understand you don't care much anymore for the discussed problem, and I know that localizing D/DMD bugs requires some time and work.
But I'd like you to not ignore all the bugs you find, and instead minimize some of them and submit them to Bugzilla. Despite thousands of open bugs and about a hundred of open patches, many bugs do get fixed at every release. If you submit bugs, D/DMD will improve, in your future you will find less bugs to work around in your D code, and you will help other present and future D programmers avoid hitting them. This is important because D is young and its community is small. The idea is: they give you a compiler/language for free, and you give something back to the community submitting some bugs :-)
Bye and thank you, bearophile
