Hi,
we reproduced the problem and below is the content of fcn:
(gdb) p *fcn
$1 = {node = {key = 2417939894599905030, left = 0x2b822d64f780, right =
0x2b822ada9a00, parent = 0x2b822bac7080, color = 0 '\000',
data = 0 '\000'}, queue = {prev = 0x2b822afd63a8, next =
0x2b822ad45040}, key = "\177\215\220\215h!?T", count = 1, uses = 1,
valid_msec = 0, error = 0, exists = 1, updating = 0, deleting = 1, uniq =
7209021, expire = 1311055359, valid_sec = 0,
body_start = 905, fs_size = 2}
(gdb)
So I guess we should apply the patch?
