%%%I accidentally SKey BEFORE LMB to set the marker.

Open movie in 'Movie Clip Editor'
'Add Marker and Move'
Move mouse over video (do not click)
Press 's' key for scale
Crashes Blender (official) 2.64rc1 2.64rc2 2.64 2.64a
Doesn't crash 2.63a
OS: winXP32

On linux (blender-2.64a-linux-glibc27-i686) doesn't crash

'Workaround' -> Press LMB first or CTRL-LMB (or use linux) =;]

%%%I can't get a crash but wondering if the crash could be caused by the large scale you tend to end up with from following these steps.

%%%It's likely out of memory issue. The thing is, when you use Add Marker and Move operator it'll create marker on position of mouse (which is behind the button). When you move it could easily be moved by couple of hundreds pixels (in clip space).
Switching to scale mode would cancel translation and switch to scale mode. Scale would happen for initially added marker and current mouse position, which could make marker around couple of hundreds pixels. Creating preview of such marker would result in memory overflow issue or it'll run really slow.

Wouldn't consider this is a bug.%%%

%%%Indeed, it also crashes when i add a marker the 'normal' way as intended: CTRL-LMB, and then SKEY, scale it really big -> kaboom. The winxp32 machine got only 3GB RAM.
Isn't it possible to prevent Blender from crashing like this:
if(mem_wanted>mem_available) {don't do the preview or paint it black; print outofmem message}

But still, why does 2.63a NOT crash?

%%%Unfortunately, there's no reliable way to detect whether you're running out of memory or not.

2.63a used completely different approach to how pattern is sampling and didn't require much extra memory on large patterns.%%%
