How to deal with bugs found in MRI while writing specs

It is often hard to know whether a particular behavior in MRI is a bug or just surprising or inconsistent behavior. If the issue is a segfault, then it is certainly a bug. If the issue is an infinite loop or threading deadlock, it is also certainly a bug. Otherwise, it may or may not be a bug. That’s up to Matz to decide.

When encountering a bug in MRI, use the following steps:

1. Search the Redmine MRI bug tracker for the same or similar behavior.
2. If there is an existing ticket for the issue, use the ticket number in a ruby_bug guard.
3. If there is not an existing ticket, file one and use the ticket number in the ruby_bug guard.
