It happens when a tooltip appears and you hover over that tooltip (try M-x locate and move the mouse around). The crash is in the line if (f && FRAME_NS_P (f)) in nsterm.m in ns_mouse_position, so apparently "f" is not NULL, but also not valid. Interestingly I can only reproduce the issue in optimized builds.

This was probably fixed with commit b4911a6f0da0bfae3832b3aa0c111db4bb2f49d5 on master. I guess we should backport the one-line initialization change onto the release branch, since the crash is nasty and the fix is trivial.
