Test case:

--------------------------------------------
void main() {
    () {
        int x;
        pragma(msg, __traits(parent, x));
    } ();
}
--------------------------------------------
Assertion failed: (next), function toDecoBuffer, file mtype.c, line 4706.
Abort trap
--------------------------------------------

The relevant stack trace:
