Unfortunately, I'm sort of stuck with this 6.3 32 bit/64 bit  arrangement for the next 6 months or more as we've a number of systems deployed.

Thanks for the reply.

Description:
       
With fair regularity, we have 32 bit processes dropping core on 64 bit 
     
systems.  In particular perl and bash.
   
Our system is definitely a hybrid but that aspect appears to not be the 
     
issue.  The system works properly more than not.
   
I have attached a file containing 2 gdb sessions. One session is looking at 
     
a core that bash left behind and the other is looking at a bash session with 
 no core.
 
 Have you tested this on 7 at all?  At this point most developers are probably 
 much more inclined to fix this for 8.0 and 7.x rather than 6.x.
