How to repeat:
1. Install Suse 13.2, apply all updates

Linux linux-85fm.site 3.16.7-7-desktop #1 SMP PREEMPT Wed Dec 17 18:00:44 UTC 2014 (762f27a) x86_64 x86_64 x86_64 GNU/Linux

2. Clone 5.6 branch from MySQL GitHub repo.

3. Compile it with option -DWITH_DEBUG=1

4. While cmake will be running it will complain about missed packages, such as ncurses-devel. Install them

5. Install MySQL server and clients somewhere

6. cd install dir/mysql-test, start any MTR test case:

./mtr --start --suite=rpl rpl_alter --mysqld=--gtid_mode=ON --mysqld=--log-slave-updates --mysqld=--enforce-gtid-consistency  --mysqld=--binlog-format=row &

7. Try to connect to MySQL server:

sveta@linux-85fm:~/build/mysql-5.6/mysql-test> gdb ../bin/mysql

Bug exists in both 5.6 and 5.7 versions. Version 5.5 is not affected (client from 5.5 can be used to connect to 5.6 server).

I couldn't repeat on OpenSuSe after a complete update (i.e I didn't get complain to install ncurses-devel).

After installing libedit-devel, libncurses6-32bit and ncurses-devel-32bit issue is resolved. You are welcome to either close the bug or change CmakeLists.txt for additional checks.

Changing category for the extra cmake checks.

Thank you for the feedback.
