When running on tvOS 10.x it crashes on a full dump when it hits NSLeafProxy in Foundation:
./classdump-dyld -o tvOSH2 -c -D

I traced the error to this section of ParsingFunctions, there may be a more proper fix to this, but this at least prevents the crash from happening and allows it to run through the full cache dump successfully.
