"too short multibyte code string" when using Pathname

[tjw@…]

Possibly related, but simpler case of  https://www.macruby.org/trac/ticket/303

See the attached script, which hits a regex parse error when run.

Digging around, it looks like this might start from lib/pathname.rb in #initialize:

if /\0/ =~ @path

raise ArgumentError, "pathname contains \\0: #{@path.inspect}"

end

The /\0/ fails to parse and a RegexpError error is thrown.

Script to show problem.

I forgot to note, this is with r2267 on the trunk (recently re-copied from the LLVM experimental branch).

Seems to be fixed in trunk as of r3858.
