Running your code I get "Can't use an undefined value as a HASH reference" (update: using warnings )

... and Perl exits "compilation exited abnormally with code 255 at Sun Dec 29 00:36:58" (update: using strict )

That's why I had to add the // {} parts in my code to default to an empty hash.

Did you tweak your Perl?

my version: This is perl 5, version 24, subversion 1 (v5.24.1) built for MSWin32-x64-multi-thread
