That was my initial guess.

Glad that Bernhard stepped up because I’ve never used FCGI. :-)

It wouldn’t even necessarily be a quick fix in this case, IMO. It
would be preferrable to fix it in FCGI, but if the maintainer is
gone and a new version is not likely to happen, then downgrading
in the FastCGI engine would be the correct and proper fix. Any
fix in the XS code would effectively imply a transient downgrade
anyway. If the body string represents an encoded octet sequence,
then downgrading will always succeed, as well.
(If it’s not downgradeable, then the engine should probably throw
an exception, as mentioned in the other thread.)
