>Description:
g++ 3.2 and 3.2.1 appear to compile Qt 3.1 OK (also the release
candidates for Qt 3.1) but a KDE compiled against it fails. The
same Qt and KDE versions work with the same compiler flags when
compiled with g++ 3.1.1 on my desktop. Since Qt and KDE are so
complex, I didn't want to report this, but now I compiled xca
(http://www.hohnstaedt.de/xca.html) and it also mysteriously
segfaulted. It worked fine when compiled on my desktop with g++
3.1.1, though.
I am using glibc 2.2.5.
>How-To-Repeat:
I hope you can repeat it by compiling Qt 3.1 and xca with the
default compiler flags.
>Fix:
no workaround known.
