[MacRuby-devel] PDFKit status?

[Laurent Sansonetti]

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.

Sometimes this happens earlier in the loop and sometimes later.  This did run a few times without error (rarely, though).  Whether or not to add .string didn't matter.  The same process works without any problem with RubyCocoa.
