Footnotemark in chapter title (memoir)

I want to add footnote to chapter title in memoir. It works as expected with numbered chapters (chapter), but shows lots of errors in unnumbered chapter (chapter*). MWE:

documentclass{memoir}

begin{document}
chapter*{this failsfootnotemark{}}
chapter[this works fine]{this works finefootnotemark{}}
end{document}

There are more than 100 errors, but first is The control sequence marked <to be read again> should not appear between csname and endcsname.

What can be a solution?
