Description:
The server crash when start with skip-grant_tables, and then run a command like "alter user 'root'@'localhost' password expire;"

How to repeat:
as above

my make and run OS
Linux  2.6.32-220.23.1.tb704.el6.x86_64 #1 SMP Thu Aug 23 17:16:25 CST 2012 x86_64 x86_64 x86_64 GNU/Linux

Suggested fix:
When start with skip-grant_tables, this command should be prevent like other grant operations, and returns "ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement"

Thank you for the bug report. Reproducible on recent 5.6.

Noted in 5.6.11, 5.7.1 changelogs.

If the server was started with --skip-grant-tables, ALTER USER ...
PASSWORD EXPIRE caused the server to exit.
