I don't think is a regression. It ICEd on DMD 0.175 (25 Nov 2006):

Assertion failure: '!scope' on line 195 in file 'toobj.c'

The current behaviour was present in DMD1.000 (2 Jan 2007). So I think it changed from ice-on-valid-code into rejects-valid.
Original test case:

template FFF()
{
 class A : B { }
 class B { }
}

void main()
{
 mixin FFF;
}

The code now compiles in D2, closing as fixed.
