Actually a regression is exactly what you though it is. A bug that was
introduced in release A and was not in release A-1 is called a
regression in release A.

My apologies, I'm a bit new to all this. If a regression means a problem
that was previously fixed but is now recurring, then it's not a
regression. I've changed the bugzilla entry to reflect that it's a new bug.
I appreciate that reproducibility is key to fixing any issue, however
it's difficult for me to reduce the code that it occurs in. I was hoping
the backtrace might provide a clue to someone who had been making
changes in that area (the crash is always preceded by GC operations).
My program consists of 4800 lines of code and much of that is a homespun
concurrency framework. Given that no one else is reporting problems with
threading I am skeptical about being able to create a simplified
reproduction.
From my point of view I'm happy to keep using an older compiler that
doesn't manifest this bug. If the problem doesn't go away in future dmd
releases or other people start experiencing seemingly related issues
then I'll definitely want to increase my efforts.

I can't seem to connect to

<http://d.puremagic.com> to file a bug, but the final beta
(and the previous one) are giving me new problems. My code
fails most of the time with exceptions from within threads,
for example:
Thread died unexpectedly:

Not sure what other information might be useful.
