I am totally lost on why this is happening.
I stripped the code down to what appears to be the most minimal
code that still causes the problem.

The beginning of the output for this code is:
a1-0
a2-0
a2-0
b1-0
b2-0
b2-0
a1-1
a2-1
a2-1
Why is the "a2" and "b2" writeln being repeated?!
I don't know, but I can't reproduce either with dmd or ldc. What
was your compilation line?
