Hi all, I have a confirmation... The problem is with libxml-ruby invoked by io.popen. If we try with Nokogiri all is ok.
So, do you think I have to submit the problem to libxml-ruby gem team or do you think it may be a problem related to io.popen ?

I attach some files to reproduce and document it.

Bug #11909: io.popen problem in 2.2 and over

----------------------------------------
Hi, I have a ruby program (prova5.rb) that contains libxml prase and a find. With Ruby 2.1.8 I have no problem, even if I execute it via "ruby prova5.rb" than if I execute it via io.popen in prova2.rb.

In a 2.2.4 environment I have success if I execute "ruby prova5.rb", but xml find stucks if I execute it via prova2.rb.

I attach prova5.rb, prova2.rb out218.txt and out224.txt.

Same problem in all 2.2 versions.

Thanks
