FBMemoryProfiler crash with __NSCFCalendar，_screenPageMap.

[c-xiaoqiang]

I have test the FBMemoryProfiler in my project and cause some crash:

1. FBObjectiveCObject ->subobject->0xffffffffffffffff & namePath = @"_screenPageMap":

when I filter it the crash fixed.
if ([self.namePath[0] isEqualToString:@"_screenPageMap"]) { NSLog(@""); return retainedObjects; }

1. FBAllocationTrackerManager:- (NSArray *)instancesForClass:(__unsafe_unretained Class)aCls inGeneration:(NSInteger)generation
   
   

in FBAllocationTrackerImpl std::vector<id> instancesOfClassForGeneration I filter it with code:
if ([NSStringFromClass(aCls) isEqualToString:@"__NSCFCalendar"]) { return std::vector<id> {}; }

then my project run complete with retain cycles button tap.

Quite interesting. I will look more closely into that. While your workaround is fine, I'll try to find a root cause of that. If we're unable to avoid that, we can just filter it out.

Thanks for reporting!
