Hi,

Could you try to find a relatively simple script that reproduces the
problem?

[Message part 1 (text/plain, inline)]

Apparently it is sufficient to upgrade packages libruby1.8,  ruby1.8 and 
ruby1.8-dev to encounter the bug.

It is possible that bug is actually caused only when you use libxml-ruby1.8.
Maybe it is worth mentioning that original script used libxml, but didn't fail 
while using libxml (line in script).

Here is script that reproduces the bug:

#!/usr/bin/env ruby

require 'xml/libxml'

i = 0;
while true
	doc = XML::Document.new;
	doc.root = XML::Node.new('gc-bug');
	i += 1;
	puts "***************** #{i} *********" if i%100 == 0;
end


And output on my computer:
$ ./gcbug.rb
***************** 100 *********
***************** 200 *********
***************** 300 *********
***************** 400 *********
***************** 500 *********
***************** 600 *********
***************** 700 *********
***************** 800 *********
***************** 900 *********
***************** 1000 *********
***************** 1100 *********
***************** 1200 *********
./gcbug.rb:8: [BUG] object allocation during garbage collection phase

Correction, this is simplest script that reproduces bug:

#!/usr/bin/env ruby

require 'xml/libxml'

i = 0;
while true
	XML::Document.new;
	i += 1;
	puts "***************** #{i} *********" if i%100 == 0;

The following script that uses the ruby cairo bindings produces the same
error for me using 1.8.7-2. Is it maybe an issue with c bindings in
general?

#!/usr/bin/env ruby

require 'cairo'
require 'stringio'

i = 0;
while true
  output = StringIO.new
  surface = Cairo::PDFSurface.new(output, 100, 100)
  context = Cairo::Context.new(surface)
  i += 1;
  puts "***************** #{i} *********" if i%100 == 0;
end

Hi James,

We are going to upload a new version of Ruby to unstable soon
(1.8.7.37-1). We are just waiting for a transition to finish. Let's see
if it's fixed with this version, and then we can try to contact
upstream.

No probs. I've downgraded to 1.8.6 for the moment, so I'll wait until I
see the new package enter unstable and give it a go.

Thanks for the testcase. I reproduced the problem with 1.8.7.17. Arg.
I also rebuilt libxml-ruby to make sure it wasn't caused by a subtle ABI
change, but the problem is still there with a freshly build libxml-ruby.

Akira-san, Daigo-san, could one of you raise the issue on ruby-dev? Or
should I raise it on ruby-core?

A guy I know replied. It is up to LibXml which is doing wrong. As the error
message says, object allocation by LibXml should not be performed during GC.

As of ruby 1.8.7, it exactly checks this issue and will report the bug message
if it finds.

Apparently the cairo bindings have the same problem....

I hope it's limited to cairo + libxml!

OK. Annoying in some ways, but nice to have narrowed the source down
somewhat. I'll see if I can get in touch with the rcairo developer.

My b.d.o foo is weak, otherwise I'd clone the bug and reassign it to the
right packages. Sorry!

For anyone doing further research, here's the bug on rubyforge that
prompted the addition of the check in 1.8.7:
