           Summary: GCC: 14: internal compiler error: in make_ssa_name_fn,
                    at tree-ssanames.cc:354
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c

When compile this program with `gcc-14 -O1`, gcc ICEs:
```
extern void abort(void);

int test(int *n) {
  struct T { char a[*n], b[*n]; };
  return sizeof(struct T) - sizeof(struct T);
}

void f1(int *p) {
  if (test(p)) abort();
}
```

The crash output:
```
during IPA pass: inline
In function 'test':
