Bug #88336 myisampack reports "error 140 on open"

Description:
myisampack included with MySQL 5.6.38 appears to be broken.

How to repeat:
Create a table:

USE db1;
CREATE TABLE tab (id int primary key, str varchar(50)) ENGINE=MyISAM;

Then run myisampack:

cd /var/lib/mysql/db1/
myisampack tab.MYI

This fails:

# myisampack tab.MYI
tab.MYI gave error 140 on open

Suggested fix:
myisampack should work in this case.

Hello Montee,

Thank you for the report.
Observed that myisampack from 5.6.38/5.7.20 affected.

Thanks,
Umesh
