When debugging the problem, I noticed that the following piece of code
from dl-open seemed to assign the wrong address:
/* We have to find out from which object the caller is calling.
Find the highest-addressed object that ADDRESS is not below. */
call_map = NULL;
for (l = _dl_loaded; l; l = l->l_next)
if (l->l_addr != 0 /* Make sure we do not currently set this map up
in this moment. */
&& caller >= (const void *) l->l_addr
&& (call_map == NULL || call_map->l_addr < l->l_addr))
call_map = l;
