Source: qt4-x11 Version: 4:4.7.3-8 Severity: important Tags: patch Dear Maintainer,
Due to a bug in the g++-4.4 optimizer, the normal "-O2" build of "qt4-x11" binary packages results in segfaults on the alpha architecture when apps are run that use the "qt4" libraries. This includes "kdm" and the KDE4 "plasma-desktop" at a minimum (bad behavior verified and easy to reproduce). A verified workaround is to build with "-O0". Note that DEB_BUILD_OPTIONS=noopt is ignored by the QT build system: I ended up editing the appropriate files under "mkspecs" directly to test the workaround. Unknown whether use of gcc/g++-4.6 fixes the issue. -- System Information: Debian Release: wheezy/sid APT prefers unreleased APT policy: (500, 'unreleased'), (500, 'unstable') Architecture: alpha Kernel: Linux 3.2.0-rc1 Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash -- To UNSUBSCRIBE, email to debian-qt-kde-requ...@lists.debian.org with a subject of "unsubscribe".
