Could you give us _any_ kind of test case (even if it's enormous)?
Bartosz - are you able to provide a test case as requested by Don ?
Then it might be possible, to get this bug fixed.
Nick B.
I can send you the files I have checked out.
The problem was in core.thread. I tried to implement a struct Tid
(thread ID) with reference-counting semantics and deterministic
destruction. It passed all the tests, but when it was used in one
particular place in druntime it produced incorrect assembly. Even the
slightest change made the bug disappear, so I wasn't able to
reproduce it under controlled conditions.
Unfortunately, I have undone some of my changes trying to bypass the
bug, so at the moment I don't even have the buggy version, but it can
be reconstructed. We can discuss it off-line, if you want. Use my
email address with -nospam removed.

I think that Don is the best person to contact you. I will try to
contact him.

Don, are you able to contact Bartosz, re the details of this test case.

Bartosz has sent it to me. I can reproduce the error. It's my top
priority, but it'll take a while -- it's nasty.
