%%%With svn trunk r41440 (64-bit linux build) release editing mesh with some modifier combinations seems to crash the Blender.

Quickest way I found to repeat the crash every time is with following steps:

Open blender with default cube scene
Add a mirror modifier to cube
Add a solidify modifier to cube
Go to edit mode and remove the top face -> instant crash

(if solidify modifier is added before mirror modifier blender doesn't crash)

I comfirmed that I'm not the only one having this problem and here's a stack trace provided by other user with svn trunk r41438 debug build:
