Can you please cut it down to a small test case? Thanks!

I know that there should be a small test case.
I hoped that debug version of dmd will clear the situation quickly.
Didn't it help?
If you really need a test case, I'll make it... one day...

Created an attachment (id=252)

testcase

Is it small enough?

Whoa, I've found it.

extern(Windows):
void  fun(PRPC_RUNDOWN);
alias void function() PRPC_RUNDOWN;

I ran into this bug too. When investigating it I found that it happens if an alias for a function pointer type is forward referenced, except when the type is "void function()". Surprisingly, changing the type into a delegate type will make it compile.

The minimal test-case seems to be:

Fn f;
alias int function() Fn;


Btw: For DMD 2.023 the assert is at mtype.c:1103.
