Emerge of x11-libs/qt-4.3.3 hangs during compilation with gcc 4.3 if optimization is set to -O2 or -O3 on my Core2Duo laptop. The last output during emerge is "floatmath auto-detection...

Try x11-libs/qt-4.3.4 with the patch in bug 214223
(In reply to comment #1) > Try x11-libs/qt-4.3.4 with the patch in bug 214223 > qt-4.3.4-r1 compiles fine with gcc 4.3 and -O2. Should bug 198121 depend on a version bump of qt to 4.3.4 stable? Or just close this bug?
Just an FYI. Pentium3 ... Compiling =x11-libs/qt-4.3.3 segfaults while compiling (during test compiles?) using either -O2 or -O3 using gcc-4.3.1-r1.

I can confirm that qt 4.3.3 builds with gcc 4.3.1-r1 with using CFLAGS="-march=athlon64 -O1 -pipe -msse3" but will not build with -march=athlon64 -O2 -pipe -msse3
I can compile it with: "-march=core2 -O1 -pipe -fomit-frame-pointer" or with "-march=core2 -O2 -pipe -fomit-frame-pointer -fno-strict-aliasing" qt-4.3.4-r1 ebuilds and above force the "-fno-strict-aliasing" flag into the package, but qt-4.3.3 still doesn't..
I had the same problem, but putting -fno-strict-aliasing in the CFLAGS fixed the issue. So maybe the ebuild for qt-4.3.3 should be changed such that -fno-strict-aliasing is added to the CFLAGS?
