I am getting a crash on the just newly released neovim 0.8.1 :
$this->bbcode_second_pass_code('', '% nvim
zsh: bus error (core dumped)  nvim
')
it seems to happen on hlattrs2dict : 
$this->bbcode_second_pass_code('', '

not sure if that's specific to the package or something to be reported  on the nvim github issue
