New description:
Cocoa application built using MacRuby r746 on OS 10.5.5 with a Core 2 Duo
MBP with 4GB of RAM.
I am invoking a ruby proc using performRubySelector as follows:
{{{
#!ruby
callSelector = @selector(call:);
proc = [[MacRuby sharedRuntime] evaluateString:[NSString
stringWithFormat:@"proc %@", source]];
return [proc performRubySelector:callSelector
withArguments:_arg1_,_arg2_,nil];
}}}
in this case I am passing two Objective-C objects, part of my application
data model, into the proc. The source of the proc is:
{{{
#!ruby
do |generateTool,player|
if rand < 0.5
generateTool.directionKnob.value = 1
else
generateTool.directionKnob.value = 5
end
end
}}}
At some point the application crashes with the following stack trace:
