--- Comment #2 from xicojovor at dropjar dot com ---
The minimal example is:


int main(void)
{
    return 0;
}

void* get_self_address(void)
{
    return (void*)get_self_address;
}


compiled with -marm -Os -fPIC

working good (maybe not the best) with gcc 4.5.4, and not ok with gcc version
5.4, 6.3.0, 10.2, 10.3.
