You can buffer overflow in fil-c and it won't detect it unless the entire buffer was its own stack or heap allocation with nothing following it (and also it needs to be a multiple of 16 bytes, cause that's padding that fil-c allows you to overflow into). So it arguably isn't much different from wasm. Quick example: typedef struct Foo { int buf[2]; float some_float; } Foo; int main(void) { Foo foo = {0}; for (size_t i = 0; i < 3; ++i) { foo.buf[i] = 0x3f000000; printf("foo.buf[%zu]: %d\n", i, foo.buf[i]); } printf("foo.some_float: %f\n", foo.some_float); } This overflows into the float, not causing any panics, printing 0.5 for the float.
