FBRetainCycleDetector Crashing

[vsravan]

I have same issue.
I have Integrated FBMemory Profiler In our App till now it is good it shows Retain Cycles. Recently we have update to Swift 4.0 compiling Our App from Xcode 9.2 With FBMemoryProfiler when I'm Clicking on RetainCycle Button App is Crashing.

I have also crashed in ios8.3,

[megCanicalKb]

Yeah the crash on [top nextObject] and FBWrapObjectGraphElement is something known but we haven't managed to fix it. Feel free to try finding a fix for this :)
