Don't know if it deserves a ticket, so I'm posting here first. I'm trying to use ObjectiveFlickr from my MacRuby project: http://github.com/czak/flickrtest One of the ObjectiveFlickr delegate methods receives NSUIntegers from the library: http://github.com/lukhnos/objectiveflickr/blob/b480aa39fa0e96f40a1b44523e0b6... When I implement the delegate method in ruby (even an empty implementation): http://github.com/czak/flickrtest/blob/00ad51b155b65221770aa4ab1661fd99957a6... ...I get a crash saying: Program received signal: “EXC_BAD_ACCESS”. warning: Could not find object file "/private/tmp/mrr/trunk/array.o" - no debug information available for "array.c". warning: Could not find object file "/private/tmp/mrr/trunk/bignum.o" - no debug information available for "bignum.c". warning: Could not find object file "/private/tmp/mrr/trunk/class.o" - no debug information available for "class.c". ... (a total of about 80 warnings for missing *.o files) Lukhnos (the author of ObjectiveFlickr) suggests it might be a case of primitive C types being passed to the delegate. Please advise - is it a bug in MacRuby that I should submit a ticket for or is there a way to avoid that? -- Regards, Łukasz Adamczak
