Crash on touch: TypeError: Attempted to assign to readonly property in ResponderTouchHistoryStore.js

[maxdjohnson]

We're seeing this mysterious crash in our production app. It happens seemingly at random, when the user drags in the app. I don't have a clean stack trace, but the error happens in the React codebase, here: https://github.com/facebook/react/blob/v0.14.7/src/renderers/shared/event/eventPlugins/ResponderTouchHistoryStore.js#L123
Looking at the code, I'm not sure how this could be happening - I suspect it could be a bug in JSC. Possibly related: https://bugs.webkit.org/show_bug.cgi?id=138038

Last seen in React Native 0.22, React 0.14.7, and iOS 9.3

we have seen this too (and at the EXACT location you pointed at).

using RN 0.22.2

That linked JSC bug sounds like it was fixed in time for iOS 9 so I don't think that's it.

We're seeing this as well, using RN 0.22.

Good catch @drtangible - going to close this out since it's believed to be fixed in RN 0.24
