            Bug ID: 112365
           Summary: [14 regression] ICE on invalid C++
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: sjames at gcc dot gnu.org
  Target Milestone: ---

This came from a (bad) reduction from a user downstream for another bug we'll
file shortly.

```
template <typename> struct ResolvedColorType;
         template < typename ColorType > ResolvedColorType< ColorType >
resolvedColor(ColorType;
         template < typename ColorType > struct ResolvedColorType {
  constexpr ResolvedColorType : ColorType {}        }
         struct {                 resolved( {
  resolvedColor(this)
```

```
