Hi all,
When developing a test case for closing a tab page with the temporary
autocmd window when executing an autocmd, I ran into a Vim crash.
The test function that I used is below:
func Test_close_tabpage_with_aucmdwin()
edit one.txt
tabnew two.txt
augroup aucmd_win_test
au!
au BufEnter * if expand('<afile>') == 'one.txt' | tabfirst | tabonly |
endif
augroup END
doautoall BufEnter
augroup aucmd_win_test
au!
augroup END
augroup! aucmd_win_test
endfunc
call Test_close_tabpage_with_aucmdwin()
The crash backtrace is below:
