hello,

I’ve got this error message from my script:

/usr/lib/ruby/1.8/pp.rb:490: [BUG] object allocation during garbage  
collection phase  
ruby 1.8.7 (2008-06-20 patchlevel 22) [i486-linux]

Can anybody tell me what I should do with it? Is there some email  
address where I should report it?

regards, Ruud

Sorry for my previous post.

More info:

the problem arises when I do this in the script (which contains a  
Test::Unit::TestCase):  
require ‘xml/libxml’  
require ‘test/unit’

class Test  
def create (file)  
doc = XML::Document.file( file)  
return ‘test’  
end  
end

class TC\_s \< Test::Unit::TestCase  
def test\_error  
t = Test.new  
res = t.create( ‘mytest.xml’)  
assert\_equal( res, ‘blip’)  
end  
end

THe error only occurs if the assertion fails, so assert\_equal( res,  
‘test’) would not raise the error. It seems that the libxml library  
does something that is not OK.
