I agree with your suggestion.
gcc(1)
-Wno-free-nonheap-object
Do not warn when attempting to free an object that was not
allocated on the heap.
The above is a non-default option.
$ cat free-test.c
#include <stdlib.h>
int main () {
int arr[] = {1,2};
int * p = arr;
free(p);
return 0;
}
$ gcc -Wall -o free-test free-test.c
$ ./free-test
Segmentation fault (core dumped)
$ gcc -Wall -Wfree-nonheap-object -o free-test free-test.c
$ ./free-test
Segmentation fault (core dumped)
$ gcc -Wall -Wno-free-nonheap-object -o free-test free-test.c
$ ./free-test
Segmentation fault (core dumped)
$
It seems to me that the option "free-nonheap-object" does not work in gcc.
