When I imported a unencrypted tablespace to a encrypted tablespace , I wish mysqld make an error, but it crashed.
The follow is the stack infomation when mysqld crashed.

#1  0x0000003e24c34105 in abort () from /lib64/libc.so.6

How to repeat:
create database if not exists test_db;
use test_db;
create table tb1(id int primary key,c1 int);
create table tb2(id int primary key,c1 int);
insert into tb1 values (1,1);
insert into tb1 values (2,2);

-- session1
flush table t1 for export;

-- session 2
alter table t2 discard tablespace;

-- session3
cp tb1.cfg tb2.cfg 
cp tb1.ibd tb2.ibd

-- session2 crash
alter table t2 imprt tablespace;
