I believe this to be a defect in WebCore due to compiler optimization in release mode. It affects FNC Core JSON when it tries to save a generic dictionary.
This only occurs in Release. if you remove optimization the bug goes away.
Possibly if some dummy code is added in the Persistence unit the compiler would not eliminate this.
Minimal sample:
