ruby (1.8.4) is crashing when it is compiled on 64-bit when caching is  
used while fetching data through oracle.  
the same works fine when ruby is compiled in 32-bit.  
The platform is Sun OS 64-bit SPARC. But it is also reproduceable on  
Linux 64-bit Server.  
Here is the error:

/home/venkatr/lib/ruby/1.8/yaml.rb:133: [BUG] Segmentation fault  
ruby 1.8.4 (2005-12-24) [sparc-solaris2.10]

gem env output:

This is urgent. Hence, any help would be greatly appreciated

Did you try strace’ing it in Linux?

(Or truss in Solaris)

Where does it die?
