Package: libqt4-dev Version: 4:4.7.2-4 Severity: serious Forwarded: https://bugs.launchpad.net/ubuntu/+source/gcc-4.5/+bug/675347 Owner: modax@debian.org File: /usr/include/qt4/QtCore/qatomic_arm.h Tags: wheezy sid Justification: makes other packages to FTBFS on armel with gcc 4.6 Hello, some QBasicAtomicInt functions do not build on armel with g++ 4.6 (Debian's g++-4.5 seems to work), for example QBasicAtomicInt::fetchAndStoreOrdered() [1]. While according to the Ubuntu report this one is forwarded to, the bug probably is in the gcc itself (broken -fstrict-volatile-bitfields handling in some cases), gcc upstream did not fix it in 4.6 despite efforts of Ubuntu people [2]. This issue will trigger many Qt based packages to FTBFS (like kde4libs [1]) because offending code is inlined in the headers. So we need a solution quick and fast, either in gcc or Qt (or both). I'm going to work on Qt solution and already have an idea how to fix this problem (a "hack").
