Created an attachment (id=518)
The simple example that shows the error.

I have attached two files, both simple code illustrating the error I've run
into. In the testAssociativeArrayFails.d file, there is a foreach block that
iterates through an associative array. If that foreach block is removed, the
file compiles fine. The error is not really meaningful and I imagine the
assertion errors in the compiler should not happen.

To help show what is causing the bug, I wrote the same sample class without
using a Variant internally in my class and everything works fantastically. I
put a shitload of time trying to figure out the error in a much more
complicated program - this error just started when I upgraded to the newest
version of DMD 2.x. I hope you can make use of my example code.


When I run the attached files, this is the output:
-------------------------------------------------------------------------------
