Indeed, this second example segfault in list_remove. But not your
first one, which segfaults on the fn(...) call inside list_remove.
And the fn parameter is _alpm_db_cmp.
Try this :
void *data;
l = alpm_list_remove(l, &a, compare_int, &data);
void *data2;
l = alpm_list_remove(l, &a2, compare_int, &data2);
