State-Changed-Why:
    Hi,
    
    Thanks for the problem report.  Unfortunately, I
    am unable to reproduce the bug with the code you
    attached:
    
    1) The RELEASE and DEBUG codes you talk about are
       not in the preprocessed source.
    2) The code you provided seems to rely on other
       compilation units, i.e. there are undefined
       references at link time.
    
    Can you produce a smaller test case, or at least one
    without external references?
    
    Oh, and I suppose you see this problem with -O3 as 
    well?  The highest optimization level for GCC is -O3,
    if you do -On, n>3, nothing extra happens.
    
    Greetz
    Steven
