Have you checked whether this still happens for you in the current test builds (

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.

hi, i tryed yesterday the newest daily release of 7.8.2016. just found out how to reproduce it. if i click on frame and value and decrease it till it hits 0 on timeline then it crashes, blender immediatly closes... here is screenshot and blend file{F334245}

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.

@Campbell Barton (campbellbarton), AFAIR, multibut edit is your area, mind having a look here? Or maybe @Julian Eisel (Severin) likes such a reports?
