Have you checked whether this still happens for you in the current test builds (https://builder.blender.org/download)?

I can't reproduce any crashes here from a clean file in current master. If you're still having crashes, could you upload a file where this is happening so that we can check if there are any other hidden factors at play here.

Ah.. you need to drag down (to start dragging both) before starting to move left/right. Indeed this crashes. Will investigate :)

This is use-after-free issue.

@ideasman42, AFAIR, multibut edit is your area, mind having a look here? Or maybe @JulianEisel likes such a reports?

An update:
So this seems to happen when you move the keyframe past the other keyframes, triggering the keyframe sorting (sort_time_fcurve()) . Disabling that step solves the crash here, but is kindof undesirable in that the curve doesn't get resorted/recalculated.

Do we have any callbacks that we only run after all interaction with a button is finished? If we do, we could just defer this curve sorting till then?

Committed fix, though the case of buttons force-exiting drag isn't well supported (undo pushes aren't made for eg).

Ideally it would work so this case would have the same logic as releasing the mouse cursor.
