agoo: Segmentation fault

I’m not 100% sure that this is an issue with Agoo, but I never encountered segfaults with Puma and they only started showing up after I switched. I can’t seem to reliably reproduce the problem, but seemingly random navigation around my app will segfault and crash the server.

Here's the segfault crash log

server.rb:47: [BUG] Segmentation fault at 0x0000000000000000
ruby 2.6.4p104 (2019-08-28 revision 67798) [x86_64-darwin18]

I left off the loaded features because it’s like 1100 lines but I’m happy to add them here if it’d help. Is there anything you can glean from this crash log? Is it possible that this has nothing to do with Agoo?

Thanks for taking a look, I appreciate it!
