I believe this is a usage issue. The key is constant, so the pointer you pass to the hashmap_foreach() macro for the key parameter must be a constant value. Unlike most data structure libraries available in C that use void pointers, this library will produce a compile warning like this for incorrect or unsafe usage.

const int *key; /* This is a pointer to a constant key type */
struct my_value *val;

hashmap_foreach(key, value, &map) {
    /* ... */
}

I checked my code and yes: I mistakenly didn't declared the key as a constant value; I guess i "payed" my lack of experience debugging complex C code. Thank you for the correction, have a nice day!
