Perhaps you can let me have an idea of the kind of code that is doing 
this?  Is this a continuation of the derived type problem or did it 
exist prior to the patch of a week back?

A good starting point is to use gdb on 
$yourgccpath/libexec/gcc/i*/4.2.0/f951 ;
Then run "command line"

Best regards

Paul
