Summary: Opening many files causes segfault on fbsd-amd64
Initial Comment:
I have a number of xml files I'm parsing, and it seems the libxml-ruby will
cause a segfault if I open too many files too quickly.
For example, if your script test.rb is:
--
require 'xml/libxml'
(1..10000).each{|time|
XML::Document.file('test.xml')
p time if time % 100 == 0
}
--
and test.xml is
--
<?xml version="1.0"?>
<test/>
--
Then, on fbsd-amd64, you'll see
100
200
300
400
500
test.rb:5: [BUG] Segmentation fault
ruby 1.8.5 (2006-08-25) [amd64-freebsd6]
zsh: abort (core dumped) ruby test.rb
It seems to error in the same place every time. Interestingly, for so short an
XML file, if you remove the if clause from the p statement, there won't be any
errors, however longer XML files will still suffer this problem. More
interestingly, the problem can be avoided entirely by disabling the GC.

I assume this is now fixed with the new memory model.

Here's the error log. I don't know what'll happen to the formatting, though:

I think I'm also facing a similar issue. I'm on a 64 bit Intel machine with
libxml-ruby-0.5.2. I'm trying to write a long running RESTful service in Rails.
After the first few XML POSTs to the Rails server, it suddenly segfaults.
I can attach the error log. How do I attach a file?

There is a new memory model released but I do not have this system combo to
test. Please take a few minutes and go to the project page and download the
MEM2 release 0.5.0 and run the rwtest/doc_file.rb from the 'ext' directory (to
use the local build instead of a system installed libxml). Please follow up.
