I have found, that problem is in "default" property of Text::Xslate::Compiler attributes.
Under threads default value is not applied for some reasons.
If I rewrite attribute declaration to use "lazy" and "builder" - everything works.
Maybe the problem somewhere in Mouse?
Maybe it time to apply Moo patch? ;-)
