            Bug ID: 120024
           Summary: ICE (Segmentation fault) in expand_call when casting
                    malloc to void (*)(void) and calling it
           Product: gcc
           Version: 15.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mario.rodriguezb1 at um dot es
  Target Milestone: ---

The following valid (but nonsensical) C code triggers a segmentation fault and
an internal compiler error (ICE) in GCC:

```
#include <stdlib.h>
int main()
{
    ((void (*)(void))malloc)();
    return 0;
}
```

To reproduce quickly:

I have tested all x86-64 gcc´s and the error arises in all of them.
