Hi Laurent and Matt,
I tried the script with GC_DISABLE=1 (I'm not sure if this is how it should be,
though), and with GC_DISABLE set to 1, the script run without any problem. As
with my first post, 'sample.pdf' is a 12000 word academic journal article PDF
in English.
I also tried .map{|x| x.string} as well as .each{} and got the same results
(error). I got error something like 9 out of 10 times. When I didn't use
block, the script run without any error (even without GC disabling)
Should I go ahead and file a ticket?
$ GC_DISABLE=1 macruby sample.rb
sample.rb
#!/usr/local/bin/macruby
framework 'cocoa';framework 'Quartz'
PDFDocument.alloc.initWithURL(NSURL.fileURLWithPath("sample.pdf")).findString("the",withOptions:NSCaseInsensitiveSearch).each{|x|
p x.string}
The error messages I got are (multiple, all while processing the block):
=> NSInvalidArgumentException: -[CPCharacterIndex count]: unrecognized selector
sent to instance (RuntimeError Error)
=> NSRangeException: *** -[NSCFArray objectAtIndex:]: index (220) beyond bounds
(2) (RuntimeError)
=> [CPZoneBorderIntersection count]: unrecognized selector sent to instance
=> Segmentation fault
Best,
Yasu
