Bug #62230 Innodb fails on any alter table statement

Description:
Any Alter table operation will fail with Error 1025 and show up as a foreign key error. This is client independent.

I've seen some bugs that involve specific alter table operations, but I can't make any changes to my InnoDB tables, not even move them to MyISAM. I have absolutely no foreign keys, it is very strange that every alter table statement should end up logged as an FK issue.

I've tried changing tables to MyISAM, changing fieldnames, datatypes, etc. The only recourse is dropping the table and recreating it. 

Here are some entries in the Log:

LATEST FOREIGN KEY ERROR
------------------------
InnoDB: Renaming table `s`.`completed` to `s`.<result 2 when explaining filename '#sql2-96c-5dd'> failed!
InnoDB: Renaming table `s`.`completed` to `s`.<result 2 when explaining filename '#sql2-96c-5e0'> failed!
InnoDB: Renaming table `s`.`completed3` to `s`.<result 2 when explaining filename '#sql2-96c-608'> failed!
InnoDB: Renaming table `s2`.`form` to `s2`.`forms` failed!

How to repeat:
Make a simple InnoDB table and try to change something (a field name).

Please, upload the entire error log of your server (compressed if it's big).

I'm going to attach some notes of interest in the log. I have to ask the sa if I am allowed to release the entire log(which contains private info,ips etc). It may not be necessary.

I think I found the problem, I removed force recovery and it seems to work now. The Foreign key error message though should be rectified...it was very misleading. Thanks....

Thank you for the feedback.

Closed as "Not a Bug" because last comment. Regarding to the message innodb_force_recovery is special option which must be used only in recovery mode and never in normal operations. Actually error log file contains proper error message:

InnoDB: innodb_force_recovery is on: we do not allow
InnoDB: database modifications by the user. Shut down
InnoDB: mysqld and edit my.cnf so that newraw is replaced
InnoDB: with raw, and innodb_force_... is removed.
