This is a test case from bug 4269, which was not fixed by the recent commit to
mitigate 4269. Note also that 4269 was a regression in 2.031, this one is far
more recent.

==============================
static if(is(typeof(X3.init))) {}
void X3(T3) { }
==============================
ICE(glue.c) for 2.047 on. It generated an error on 2.045 and earlier. (On 2.046
it silently generated bad code).



==========================================
Comment from yebblies:

The crash is due to an error in a parameter type not resulting in
TypeFunction::semantic returning terror.  (Or at least, that and the fact it
reaches code generation due to this bug.)  I swear I fixed this in
a pull request last year, but it must've been part of something that never got
accepted.
