%%%Subdivision Surface (Apply modifier to editing cage during Editmode) Crash

Whenever you use this "feature" and then try to do Ctrl+R loop cuts
with the display view subdivisions on like 2 or so,
it crashes blender.

Windows 2.63 64 bits crashes doing this
Windows 2.63 32 bits crashes as well. doing this
works fine without pressing the (triangle, leaving the editcage on the outside)
but soon as you click the triangle and try to loopcut it crashes.

i tried this on 2 systems, 1 AMD 8-Core, 1 Intel i-5(Win 7 64 on both)
Both systems also have Nvidia cards, i a 8600GT, the other a Geforce 550

%%%Umm.. it crashes on the default cube..
Just add a Sub-division surface modifier to it(with view detail set to 2 or 3)
Press the Triangle(apply edit cage during editmode)

then do a few single loopcuts..
in succession blender will soon crash.

It doesn't crash with the edit cage on the outside of the object..
but with the editcage touching the object it causes crashes. %%%

http://www.youtube.com/watch?v=Cd4cwXYkag0

That was recorded that on Windows 8.
however I now have Windows 7 64bit installed and its still doing it,
(i also tried it on another PC with Win7 and can reproduce the same crash, that PC is Intel i5)
I have installed Lubuntu 64 bit and it does it also, so its gotta be a bug. %%%

%%%Hm, cant redo here (Fedora 16 64bit gcc 4.6.3) r48086. Tested on laptop (integrated Intel graphics) and workstation (Nvidia GTX570) in both release and debug build as well as official 2.63a from b.org.

Been hammering it for 10min and all is good.

[ As a positive side-effect I got to know from holy enigmas console output what "reverse-i-search" is :) ]%%%

%%%Can not reproduce in release 2.63a Windows 64 or compiled from trunk r48125.

Could you grab a build from graphicall.org (or compile yourself) and see if you still have this problem?%%%

%%%Closing this one as no developer could reproduce and no further update from Bug Reporter. %%%

%%%Managed to redo, re-opening.

Looked into this further.

The bug is caused by 2+ events in the events system triggering an edge slide macro twice in a row BEFORE wm_event_do_notifiers() is called.%%%
