I am getting a segmentation fault during tests (line 974).  
Any ideas how I can find the cause?  
The tests worked fine on beta2

Also, for some deprecation warnings (e.g. line 949 `WARNING: Base.ObjectIdDict is deprecated, use IdDict{Any, Any} instead.`), I cannot tell whether it is from a dependency or my package.

Please open an issue. Julia shouldn’t segfault (unless you do `unsafe` things)
