pt-online-schema-change error: Error creating new table ... duplicate key

remko@paragin[email protected] EntrantInactive User Role Beginner
When using pt-online-schema-change 3.0.10 on a table that has previously been altered using the same tool, we get the "errno: 121 Duplicate key on write or update" error.
Googling & your bug tracker lead me to https://jira.percona.com/browse/PT-394, but this issue is marked as fixed while it appears that it still exists.

I found an online blog-post detailing the issue and the fix, but I'm very uncomfortable with patching the software myself.

Is there any progress or news about the issue, or do I need to assume the tool works as intended and we need to find another workaround?
