[dmd-beta] dmd 1.068 and 2.053 final beta

[David Bryant]

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.

Regards,
Dave
