This crashes the compiler:
auto bunch(T)(T[] items...) {
return ["+" : 0];
}
enum int* r = "+" in bunch(1);
void main() {}
The following variant of the same program doesn't crash the compiler, but gives a forward reference error, that seems wrong:
Error: forward reference to bunch
auto bunch() {
return ["+" : 0];
}
enum int* r = "+" in bunch();
void main() {}

This fixes the ICE:
expression.c line 7181.
----
if (!type)
{
error("forward reference to inferred return type of function call %s", toChars());
type = Type::terror;
+ return new ErrorExp();
}

This bug was about two different problems, one of them is now fixed.
So I close this bug and move a simplified version of the code that generates the error in bug 4075.
