The problem becomes visible when one tries to execute kdesktop_lock in KDE
3.5.2. No problem with gcc 4.1.1.
The attached patch for qt-3.3.6 fixes the problem.
I'm running Gentoo Linux with CFLAGS="-march=athlon-xp -O2 -pipe". The
corresponding Gentoo ebuild is qt-3.3.6-r1.

We need a self contained testcase for this issue.
Really reporting 3.4.x bugs means you will not see this fixed as 3.4.x is no
longer supported.

So you have a long-developed and relatively stable and good compiler and you
don't develop it any more? Not good. The 4+ branch is pretty unstable. I had
to downgrade the gcc 4.1.1 compiler on my Athlon XP and on my VIA C3 systems
because the systems randomly just hard-locked since the upgrade and the
recompilation of the packages.
I will not give an isolated test case, but the information on
http://bugs.gentoo.org/show_bug.cgi?id=133301 may even help more.

Note: the words "under hardened" in the title of the Gentoo Linux bug report
are wrong -- the problem also occurs with a plain vanilla/non-hardened gcc.

SSP is not part of GCC until 4.x so we really cannot support that. And it was
rewritten to be better anyways. So this is not a bug.

Like I already said, this has nothing to do with hardened extensions. Look at
my patch. It is a problem related to the parser: bad code gets produced when
"XWindowAttributes a;" is not at the beginning.

Waiting for a real testcase then.
