Broken: Blender 2.79b
Ctrl snapping a strip in transform / Time_Extend mode crashes Blender instantly if the time cursor overlaps the strip, so only when you're extending a video or an image strip.
It happens often but I can't reproduce the bug 100% of the time. Sometimes it'll insta crash with any strip, sometimes it'll work. Even on minimal projects, e.g. with only one video or image strip.
See attached blend
# Select a video, image or audio strip linked to an effect strip
# Place the time cursor so it overlaps the strip
# Press E to extend the strip
# Press Ctrl to snap, Blender crashes
