crash file

$ clang-tidy-10 crash.c --
produces a segmentation fault

I have tried 7, 8 and 10 with the same results.

Please see attached, and here is the minimal code:

#include <stdio.h>

void __attribute((ownership_returns(my_malloc))) *malloc(size_t amt);
void __attribute((ownership_takes(malloc, 1))) free(void *ptr);

void __attribute((ownership_returns(my_malloc))) *my_malloc(size_t amt);

void test1() {
    int *p = my_malloc(12);
    free(p);
}

int main() {
    return 0;
}


If I comment out the following line the segmentation fault goes away:
void __attribute((ownership_takes(malloc, 1))) free(void *ptr);</pre>
        </div>
