Unfortunately I don't know what is the cause of this error message but
I'd like to suggest another way of defining key maps. Instead of adding
several autocmds for a filetype it's usually more convenient to use a
custom filetype plugin file. That is, create file
~/.vim/after/ftplugin/haskell.vim and put your nmap etc. commans there:
nmap <buffer> <C-c><C-l> :GhciRange<CR>
vmap <buffer> <C-c><C-l> :GhciRange<CR>
nmap <buffer> <C-c><C-f> :GhciFile<CR>
Note that we use <buffer> keyword here so that the key maps are local to
that buffer. (And by the way, I think Vim script-writers mess too often
on global level when they should keep their mappings, variables etc. on
buffer-local or window-local level.)
