Bug#196090: gcc-3.3: miscompiles XDM-AUTHORIZATION-1 key generation and/or validation in XFree86 at -O2

[Jack Howarth <howarth@bromo.msbb.uc.edu>]

   Franz Sirl, the ppclinux devtool maintainer, has kindly
built the current rawhide XFree86 4.3.0 srpms against 
gcc-3.3 from 6/18/03 on Yellow Dog Linux. He is unable to
reproduce the authentication problems we see on debian
under either xdm or kdm. Perhaps we build XFree86 differently
enough from RedHat that only we tickled the gcc bug. However
I did find out that the gcc 3.3 that RedHat uses is not
a patched version of the gcc 3.3 branch but rather a special
rh branch of gcc-3.3. One wonders if they would see the
problem if they used the stock gcc-3.3 branch instead and
if there are any fixes trapped in the gcc-3.3 rh branch that
haven't been put into the main gcc-3.3 branch.
