imagine a setup where you have a my.cnf:


on windows the console can now not handle a command like:
mysqlbinlog ... | mysql
since it'll ask for the password twice, the windows console can't
handle it.

so, adding

would help that situation, unfortunately that seems to not really work!

How to repeat:

flupps@flupps-computer:~$ mysqlbinlog --skip-password
Enter password: 
Bus error
flupps@flupps-computer:~$ mysqldump --skip-password
Bus error
flupps@flupps-computer:~$ mysql --skip-password
(no problem for mysql)

On Linux:
flupps@piglet:~$ mysqlbinlog --skip-password
Segmentation fault

Suggested fix:
Make --skip-password work for mysqlbinlog/mysqldump just like it does for mysql

Thank you for the report.

Verified as described.

On Linux both mysqlbinlog and mysqldump are affected.

workaround: Use a user that has a password

Noted in 5.1.36 changelog.

no password." 

Setting report to NDI pending push into 6.0.x.
