Re: [Rubycocoa-talk] A potential bug to watch out for...

[Duncan M. <du...@on...>]

I've had that Xcode trace in my console (various addresses) for at  
least the past few days, before and after updating to 10.5.7, so maybe  
that isn't related to your [BUG].

My app still passes all its tests without your 'object allocation  
during garbage collection phase' issue, and, to pick one random  
example that we both could run, so does CGPDFViewer. So maybe its  
MacRuby?
