First cut, some hacks, three simple modules.

[ccan] / container_of / test / compile_fail-types.c

#include "container_of/container_of.h"
#include <stdlib.h>

struct foo {
        int a;
        char b;
};

int main(int argc, char *argv[])
{
        struct foo foo = { .a = 1, .b = 2 }, *foop;
        int *intp = &foo.a;

#ifdef FAIL
        foop = container_of(intp, struct foo, b);
#else
        foop = NULL;
#endif
        return intp == NULL;
}
