Description
Mysqld exits without anything in error log when trying to insert binary value in varchar field in CONNECT table, but only if table has primary key.
This works:
CREATE TABLE `s` ( |
`id` int unsigned NOT NULL, |
`name` varchar(255) default NULL |
) engine=connect; |
INSERT INTO `s` VALUES (1,'\0'); |
The same, except primary key on id field was added:
CREATE TABLE `s` ( |
`id` int unsigned NOT NULL, |
`name` varchar(255) default NULL |
) engine=connect; |
 |
alter table s add primary key (id); |
INSERT INTO `s` VALUES (1,'\0'); |
I don't have any message in error log, but coredump has this stack
