Hi
Command custom completion (:help :command-completion-customlist)
is leaking memory when redefining completion for a command
multiple times. I see this bug in latest Vim-7.2.132.
The following script illustrates the problem: memory usage keeps
growing at each iteration when redefining a command completion:
:function! s:Foo()
:endfunction
:function! s:CompleteFoo(a, l, p)
:endfunction
:while 1
: " Leak at each iteration
: command! -complete=customlist,s:CompleteFoo -nargs=1 Foo :call s:Foo()
:endwhile
Attached patch fixes the memory leak.
Regards
