Date: Sat, 06 Apr 2013 20:35:10 +0400
Message-ID: <51604EBE.1070306@yandex.ru>

Found 100% method to hit eassert introduced in r110971 within update_tool_bar:

1) ./src/emacs -nw -Q
2) M-x make-frame-on-display :0
3) Move mouse to new X frame and left-click;
4) Move mouse back to TTY frame and left-click;
5) Press C-g staying in TTY frame ==>
