Patch for this problem is trivial (as is for the similar mod_fcgi crash): https://redmine.lighttpd.net/projects/lighttpd/repository/revisions/5e3653dc5d00647d32d3553b639b0e195ec839f9/diff

It will be fixed in 1.4.44, however it's hard to tell when 1.4.44 “will be” and the bug is quite annoying and crippling at that.
