I strongly object to this suggestion. It clearly goes against the documentation
on the GCC web site at  http://gcc.gnu.org/gcc-3.2/c++-abi.html

FWIW, I have recently compiled qt-3.1.0 and qt-3.1.1 as well as kdelibs-3.1rc5
and kdelibs-3.1rc6 without problem. Admittedly, my system isn't strictly by the
book but the gcc is most certainly compiled with --enable-__cxa_atexit.

I suggest you need to look elsewhere for the QT uic segfault problem. Is hard to
say what the problem may be without a backtrace. But it smells like a
miscompiled glibc from this angle. Maybe the fact you recompiled glibc made the
problem go away? It would be interesting to see if you recompiled gcc with
--enable-__cxa_atexit then recompiled glibc then everything else and see if the
problem still exists. In other words, I'm speculating that your recompile of
glibc made the problem go away, and not omission of the --enable-__cxa_atexit
switch to gcc.
