State-Changed-Why:
    You state that this happened with RH 7.2 GCC, but you
    also claim that you were using GCC 3.1.  AFAIK RH 7.2
    uses their GCC 2.96.  If that is so, you should report
    it to Red Hat and I wilk close this PR.
    
    If it is a 3.1 bug, I can do nothing to fix it unless you
    give me a testcase in the form of a minimum number of files
    to reproduce.  Asking me to try some random kernel is a non-starter.
    
    Please let me know.
