------- Comment #2 from pinskia at gcc dot gnu dot org 2008-08-16 22:54 ------- __insertion_sort (&entry.node_id[0], &entry.node_id[16]);
The length is only 4. One issue is that we don't reduce: D.8167 = &entry.node_id[0] + (unsigned int) num_side_vert * 4; if (&entry.node_id[0] != D.8167) Into: if ((unsigned int)num_side_vert * 4 != 0) So I think the other issue is that the code for std::sort assumes that it will be a pointer and an array with a small size. The warning is only partly bogus but since this is only runtime undefinedness, this is valid code. The function get_int better never return more than 4 really. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37130
