          Issue ID: 23549
           Summary: assert(0) as default parameter causes segfault
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Keywords: ice, ice-on-valid-code
          Severity: regression
          Priority: P1
         Component: dmd
          Assignee: nob...@puremagic.com
          Reporter: elpenguin...@gmail.com

This code
```
void main() {
    foo(); //commenting this out lets this compile successfully
    foo(3);
}
int foo(int g = assert(0)) {
    return g;
}
```
causes dmd to segfault since version 2.098.
Up until 2.098, this produced an incorrect error instead: `Error: e2ir: cannot
cast 'assert(0)' of type 'noreturn' to type 'int'`.
