Problem: Crash when using b:, w: or t: after closing the buffer, window or
tabpage.
Solution: Allocate the dictionary instead of having it part of the
buffer/window/tabpage struct. (Yukihiro Nakadaira)
Problem: ":window set nu?" displays the cursor line. (Nazri Ramliy)
Solution: Do not update the cursor line when conceallevel is zero or the
screen has scrolled. (partly by Christian Brabandt)
Problem: Segfault when doing "cclose" on BufUnload in a python function.
(Sean Reifschneider)
Solution: Skip window with NULL buffer. (Christian Brabandt)
Problem: Segfault with specific autocommands. Was OK after 7.3.449 and
before 7.3.545. (Richard Brown)
Solution: Pass TRUE for abort_if_last in the call to close_buffer().
(Christian Brabandt)
Problem: It is possible to add replace builtin functions by calling
extend() on g:.
Solution: Add a flag to a dict to indicate it is a scope. Check for
existing functions. (ZyX)
Problem: When using :tablose a TabEnter autocommand is triggered too early.
(Karthick)
Solution: Don't trigger *Enter autocommands before closing the tab.
(Christian Brabandt)
Problem: When closing a window or buffer autocommands may close it too,
causing problems for where the autocommand was invoked from.
Solution: Add the w_closing and b_closing flags. When set disallow ":q" and
":close" to prevent recursive closing.
Problem: Crash when using ":redraw" in a BufEnter autocommand and
switching to another tab. (驼峰)
Solution: Move triggering the the autocommands to after correcting the
option values. Also check the row value to be out of bounds.
(Christian Brabandt, Sergey Khorev)
Problem: Crash when a BufWinLeave autocommand closes the only other window.
(Daniel Hunt)
Solution: Abort closing a buffer when it becomes the only one.
Problem: When closing a window there is a chance that deleting a scrollbar
triggers a GUI resize, which uses the window while it is not in a
valid state.
Solution: Set the buffer pointer to NULL to be able to detect the invalid
situation. Fix a few places that used the buffer pointer
incorrectly.
