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

Ruby
1

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’

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

Thanks in advance

Stefano

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,

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

Thanks
