Comment 1 Wormo (RETIRED) gentoo-dev 2008-10-13 20:24:19 UTC 
Can you try again with one of the gcc versions available in the main gentoo tree? I suspect a problem with the unstable version of gcc rather than the stable version of qt...
Comment 2 Hanno Zysik (geki) 2008-10-14 09:08:24 UTC 
Duplicate of bug 213411.

Append '-fno-strict-aliasing' to your CFLAGS to workaround Qt-4.3.x issue.
Qt-4.4.x should be fixed.
Comment 3 Thilo Bangert (RETIRED) (RETIRED) gentoo-dev 2008-10-14 17:45:54 UTC 
andrew: can you confirm that adding '-fno-strict-aliasing' to your CFLAGS makes this problem go away?

if so, please close this bug as a duplicate of bug #213411.
thanks.
Comment 4 Per Pascal Seeland 2009-01-02 23:22:27 UTC 
I can comfirm that the adding "-fno-strict-aliasing" enables building qt. I had the same problem andrew reported. I suggest marking it as duplicate.

Comment 5 Ben de Groot (RETIRED) gentoo-dev 2009-01-03 01:30:39 UTC 

*** This bug has been marked as a duplicate of bug 213411 ***
Comment 6 Gordon Malm (RETIRED) gentoo-dev 2009-01-03 05:18:58 UTC 
Looks like it was marked a dupe before I refreshed, so just repasting my comment:

I can reproduce this issue and can confirm that adding -fno-strict-aliasing to CFLAGS (and thus CXXFLAGS) fixes the problem.  Closing as duplicate of 213411 as requested in comment #3.

Also note that GCC 4.3.x is targeted to go stable in the not-to-distant future.  I'd recommend an append-flags be added to the =x11-libs/qt-4.3.3 ebuild or =x11-libs/qt-4.3.4-r1 be considered for test/stable very soon.
Comment 7 Ben de Groot (RETIRED) gentoo-dev 2009-01-03 14:23:52 UTC 
Actually, qt 4.4.2 is meant to go stable soon, see bug 248038. So that should solve it for stable as well.
