TestVMDump#test_darwin_invalid_call fails with Timeout::Error

I can reproduce with ruby -rfiddle -e "Fiddle::Function.new(Fiddle::Pointer.new(1), [], Fiddle::TYPE_VOID).call".
After that backtrace was stopped "C level backtrace information" section. like this

~ > ruby -rfiddle -e "Fiddle::Function.new(Fiddle::Pointer.new(1), [], Fiddle::TYPE_VOID).call"
-e:1: [BUG] Segmentation fault at 0x0000000000000001
