[Bug] IOS crash with "runtime exception"

[ddyer0]

Summary

This is a new variant of the same dictionary loading test I've been using to generate complaints.
This variant reduces the "small object" count to nearly zero, and instead uses a single scratch oject
to fill a hash table, which serializes the arguments into a bulk storage scheme.

This runs handily on the simulator and android. The same code running in my real app seems to
complete successfully, but the loading thread crashes with a "runtime exception" error, or sometimes
the app hard crashes. This transcription of the code to a test program just never completes, it
disappears during the first "put" operation.

I'm doing something new and unusual with interfaces and default methods, so it's possible this is
a code generation strategy problem. See the interface BulkableEntry
