I hit this assertion failure somewhat consistently on an iPhone 6 running iOS 8.3 after backgrounding the iOS demo app during a drift pan animation that caused more tiles to be fetched and bringing the app back to the foreground:

Assertion failed: (currentlyOn(ThreadType::Map)), function abandonVAO, file /Users/mxn/hub/mapbox-gl-native-2/src/mbgl/map/environment.cpp, line 144.

This crash happened to me while I was zooming around, not after leaving/reopening the app. Appears similar, if not quite exactly the same. (Accidentally posted this in #1277 just now.)

Assertion failed: (env), function Get, file /Users/jason/Documents/Mapbox/mapbox-gl-native/src/mbgl/map/environment.cpp, line 103.

Avoid binding a shared_ptr<TileData> in the work callback
f5ca50f 
It's possible that the work callback can outlive the after callback,
since work callback destruction and after callback execution happen in
two different threads. This could account for the crash seen in
#1309 (comment)

A potential fix for the latter crash is in f5ca50f.

More bandaids to avoid #1309
24695f6 
Even though we only bind the shared_ptr in the after callback, the
worker thread was still copying the callback and therefore gaining
a shared reference. Here we try to eliminate the copies.
