Ignore style.. this is a massively reduced case from a much more complex block
of code.
Looks like a compiler bug. If you change func2 to this:
void func2(T, U)(const T[] foos, out U afoo)
{
static assert(is(T==U));
}
test0.d(212): Error: static assert (is(const(int) == int)) is false
test0.d(207): instantiated from here: func2!(const(int),int)
test0.d(201): instantiated from here: func1!(int)
T should be "const(int)" instead of "int".
