Hi,

I am using Ruby 1.8.6 (2008-08-11 patchlevel 287) on FreeBSD 7.0- 
RELEASE-p7. I have some code that -among other things- parses XML  
files and when it does in at least one case, it dumps core with the  
following error msg:

-x-x-x-
/usr/local/lib/ruby/1.8/rexml/parent.rb:19: [BUG] object allocation  
during garbage collection phase
ruby 1.8.6 (2008-08-11) [i386-freebsd7]
-x-x-x-

At times, I get a different error msg:
-x-x-x-
/usr/local/lib/ruby/1.8/rexml/namespace.rb:16: [BUG] object allocation  
during garbage collection phase
ruby 1.8.6 (2008-08-11) [i386-freebsd7]
-x-x-x-

I initially developed my code using Ruby 1.8.6 patchlevel 111 on the  
same platform and everything worked as expected. And when I upgraded  
to the latest stable version from ports, I started having these  
issues. Staying with 1.8.6 patchlevel 111 is not an option since this  
version is riddled with security vulnerabilities.

Any ideas on how to fix this problem?
TIA.
