            Bug ID: 110737
           Summary: GCC: internal compiler error: Segmentation fault when
                    processing __builtin_isinf and _Atomic long double
                    together
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: 141242068 at smail dot nju.edu.cn
  Target Milestone: ---

When attempting to compile below program using gcc-14 with option `gcc-14
small.c`, gcc throws internal error.
```
_Atomic long double c;
void f(void);
void g(void) { __builtin_isinf(c /= f()); }
```

The output of gcc is pasted below:
```
<source>: In function 'g':
<source>:3:1: error: void value not ignored as it ought to be
    3 | void g(void) { __builtin_isinf(c /= f()); }
      | ^~~~
<source>:3:34: internal compiler error: Segmentation fault
    3 | void g(void) { __builtin_isinf(c /= f()); }
      |                                  ^~
