Bug ID: 127164
Summary: ICE on valid static compound literal at function
prototype scope
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: aaron at aaronballman dot com
Target Milestone: ---
Consider the following terrible, contrived example:
```
void func(int x[(static int){12}]) {
}
```
This currently causes an ICE: https://godbolt.org/z/Y5K84WvG1
```

This could be a duplicate of
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=109828 but I wasn't certain so I
filed it separately.
