Hi,

Is ruby 1.8.7 on snow leopard backward compatible with ruby 1.8.6 on  
leopard. I’d like to know if there are special known issues, that should  
be taken care of when porting projects, based 1.8.6 leopard to 1.8.7  
10.6? My project integrates RubyCocoa, which is a separate subject to  
check, but currently the project, that worked in 1.8.6 enters an  
infinite loop somewhere deep in RubyCocoa on 1.8.7 snow leopard. I’m  
using the same 0.13.2 version in migration.

Thank you in advance  
Nava

hm, ruby itself shouldn’t be a problem AFAIK. We had a thread about  
1.8.7  
some time ago and the general opinion was that it didn’t break anything  
but  
rather mostly add new features, thus it’s probably a cocoa issue.

Greetz!

You were right! There was an issue with RubyCocoa.
