How to repeat:
use test;
drop table keyvalue1;
CREATE TABLE `test`.`keyvalue1` (
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(40),
PRIMARY KEY (`id`)
) ENGINE=Innodb;
set @id:=0;
insert into `keyvalue1` values (@id:=@id+1,md5(rand()*1000000)),(@id:=@id+1,md5(rand()*1000000)),(@id:=@id+1,md5(rand()*1000000)),(@id:=@id+1,md5(rand()*1000000));
insert into `keyvalue1`(`id`,`name`)
select @id:=@id+1,md5(rand()*1000000) from
`keyvalue1` k1, `keyvalue1` k2, `keyvalue1` k3, `keyvalue1` k4,`keyvalue1` k5,`keyvalue1` k6, `keyvalue1` k7, `keyvalue1` k8, `keyvalue1` k9,
`keyvalue1` k0,`keyvalue1` ka, `keyvalue1` kb, `keyvalue1` kc, `keyvalue1` kd limit
50000;
// Remove keyvalue1.frm while MySQL server is running
- rm -rf /tmp/<datadir>/test/*.frm
- Bring down MySQL server, ensure it is shutdown, bring up MySQL server again( I used mysqld-debug in my tests )
// Remove keyvalue1.ibd
- rm -rf /tmp/<datadir>/test/*.ibd
- try to drop database "test"
mysql> drop database test;
ERROR 2013 (HY000): Lost connection to MySQL server during query

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
key_buffer_size=8388608
read_buffer_size=131072
max_used_connections=1
max_threads=2000
thread_count=1
connection_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 4387395 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

I believe workaround here can be to use release version of MySQL server.

Noted in 5.6.14 changelog: "An assertion would be raised in "fil_node_open_file" due to a missing ".ibd" file. Instead of asserting, "InnoDB" should return false and the caller of "fil_node_open_file" should handle the return message."
