Hi Laurent, I couldn't find a crash report in Console, but Xcode gave the following with build and debug. #0 0x7fff815020da in objc_exception_throw #1 0x7fff81af26f0 in _qfqp2_performParsing #2 0x7fff81af05b9 in +[NSPredicate predicateWithFormat:arguments:] #3 0x7fff81af057c in +[NSPredicate predicateWithFormat:] #4 0x7fff81af020d in _qfqp_InitializedGlobalData Is this of any use or do you require more info.

Hi Alan,
The crash may be a bug in the way we compile calls to variadic functions (such as predicateWithFormat:). Could you locate the crash report and copy/paste the backtrace information?

Hi everyone, Has anyone had any trouble with NSPredicate causing occasional crashes when used with NSArrayController? Well actually about 50% of the time.
What I have is a subclass of NSArrayController which is a data source for an NSTableView that accepts drag and drop operations. In 'awakeFromNib' a NSPredicate is defined, sometimes the error is just, “EXC_BAD_ACCESS”, other times there's a bit more info:
data_source.rb:20:in `awakeFromNib': NSInvalidArgumentException: Unable to parse the format string "AND" (RuntimeError)
This is the offending line: @filter_predicate = NSPredicate.predicateWithFormat("file_type == 'NSFileTypeRegular'")
The crash doesn't always occur, when it doesn't my app works without any problems. I've tried the predicate in macirb and the crash doesn't occur!?
