Hi:
it seems due to EXPLAIN , since other normal sql has a valid catalog .
and I found it also generate a segfault when linked against mysqlnd
the most difficult part is, when the catalog in field struct is
not valid, it is not a NULL pointer,,, I can't distinguish this from a
valid catalog string pointer.
(gdb) p *field
$2 = {name = 0x10007d0 "possible_keys", org_name = 0x10007e0 "", table =
0x10007c0 "", org_table = 0x10007c8 "", db = 0x10007b8 "",
catalog = 0x20200a3e6e6f6974 <Address 0x20200a3e6e6f6974 out of
bounds>, def =
0x0, length = 4096, max_length = 0,
name_length = 537542259, org_name_length = 1818311712, table_length =
1047748969, org_table_length = 762278761, db_length = 959789112,
catalog_length = 792474157, def_length = 1634298977, flags = 0,
decimals = 31,
charsetnr = 8, type = MYSQL_TYPE_VAR_STRING,
extension = 0x61696c612f3c3130}
thanks
