--- Comment #3 from Bernie Innocenti <ber...@codewiz.org> ---
In case it helps, I was able to build liblmdb with debug symbols and find the
exact point where the crash occurs:
#0 0x00007ffff75db86a in mdb_node_search (mc=mc@entry=0x7ffff16c4240,
key=key@entry=0x7ffff16c4620, exactp=exactp@entry=0x7ffff16c415c) at mdb.c:5341
5338 while (low <= high) {
5339 i = (low + high) >> 1;
5340
5341 HERE -> node = NODEPTR(mp, i);
5342 nodekey.mv_size = NODEKSZ(node);
5343 nodekey.mv_data = NODEKEY(node);
5344
5345 rc = cmp(key, &nodekey);
(gdb) p i
$6 = 0
(gdb) p *mp
$7 = {
mp_p = {
p_pgno = 42014499,
p_next = 0x2811723
},
mp_pad = 5922,
mp_flags = 641,
mp_pb = {
pb = {
pb_lower = 0,
pb_upper = 0
},
pb_pages = 0
},
mp_ptrs = {5921}
}
This seems suspicious:
(gdb) p low
$8 = 1
(gdb) p high
$9 = 2147483639
How can we get i=0 from "i = (low + high) >> 1" at line 5339?
