@pilgr This buffer underflow crash is also happening in our app as we are using SalesforceMobileSDK, which use version 2.7.1 of paper db. This issue only affected a few of our users but once it happens it will crash consistently (crash 200+ times for some of our users). Also because this crash is happening to those users consistently, the buffer underflow crash has pushed our crash per session rate to almost 4%

I can reproduce the problem 100% of the times. For me, it’s happening because I moved the class I was saving to a different package.
