Hi Yasu,
I tried your sample with a large pdf in my environment a few times and it never
crashed. But I suspect the exception you're getting is due to a memory problem,
maybe related to the GC.
Can you try setting the GC_DISABLE environment variable to 1 when running the
script?
If it doesn't crash anymore it's probably not a bug in MacRuby then. I would
try to rewrite the sample in pure Objective-C and see if the crash persists.
