I've just uploaded YAML::Tiny 1.21 to the CPAN.
This release fixes a major bug in the serialization that caused any unprintable character (which includes newlines and tab) to be serialized to a reference, which then stringified to REF(memorylocation).
Anything using YAML::Tiny for light weight serialization of arbitrary data is strongly recommended to upgrade.
The root cause of this bug was a trivial typo, with the primary cause attributed to a lack of unit tests (or even sample documents) for unprintable characters, which would have otherwise caused the problems to be picked up by routine round-trip testing.
This has also been resolved.
This bug was also the underlying cause of the CGI::Capture TERMCAP bug.
A new release of CGI::Capture has been uploaded with an updated YAML::Tiny 1.21 dependency to resolve the TERMCAP problem.
This is the final dependency issue preventing a 1.00 release of TinyAuth, which I hope now to complete shortly, after a little more polishing of error handling and the installation code.
