I believe we fixed this problem around CDK 1.2 time.  Unfortunatly I
don't remember what we did to fix the problem.  I am almost sure it has
to do with the spec file for gcc.  (not rpm spec, but the

Give the CDK 1.2 compiler a try on that code and see if it fixes the
problem you are having.  (Keep in mind that you will also need to use
the glibc provided.  The floating point printf fix effects both glibc
and gcc.)

If that does fix your problem I can help you track down the patch that
does the fix.  (It's been 6 or so months since I made these patches so
my memory is a bit fuzzy right now.)
