Simplest testcase:

unittest{}
void main() {
    __unittest1();
}


I'm honestly not sure if this is supposed to be legal code. But DMD 2.046 accepts and runs it without problems.

Regards

Oops, sorry, told a while lie.

The program compiles + runs when you pass the compiler flag -unittest, but ICEs when you don't.
