Marshal gives error when dumping and loading array with two regexps in latest ruby 1.9

I just upgraded my ruby 1.9 to the latest stable version (ruby 1.9.1-p243),
and now I'm facing a strange issue. The problem is that attempting to use
Marshal to dump and then load back an array containing two Regexps gives an
error. For example:

str = Marshal.dump [/a/, /b/]
Marshal.load str

This gives the following error:

/home/stefano/documents/scripts/prova.rb:4:in `load': can't convert Regexp
into String (TypeError)
  from /home/stefano/documents/scripts/prova.rb:4:in `<main>'

The above code worked perfectly with the previous version of ruby 1.9.1. Has
anybody noticed the same issue?

Thanks in advance

Hi Stefano,

I get the same error you do with ruby 1.9.1-p243. This code works
fine with 1.8.6.

Sorry that I don't know what might be causing this problem.

HTH,

Wayne

Since I'm not the only one to experience this issue, I'll report it as a bug.

Thanks
