<pre>I am no longer able to build LibreOffice with newer versions of clang 3.5. When
I upgraded to 3.5.0 final and 3.5.1(rc2), libreoffice generates unit test
error. I tested both the Pre-built Binaries and the Ubuntu nightly packages on
a fresh install of Ubuntu 14.4. All recent builds of clang failed with the same
unit test errors. Reverting back to an earlier build, always resolves the
issue.
Steps to reproduce:
1. $ git clone git://anongit.freedesktop.org/libreoffice/core
2. $ git checkout libreoffice-4-4-0 (optional, master fails with same errors)
3. $ apt-get build-dep libreoffice ( also lo_usefull Shell Script if missing
dep)
4. Remove ccache if it's installed ( ccache generates warning w/ clang)
5. create file autogen.input with CC=clang and CXX=clang++
6 ./autogen.sh && make
Results:
clang 3.5.0 svn201651 - SUCCESS
gcc 4.8.2 - SUCCESS
gcc 4.9.2 - SUCCESS
clang 3.5.0 RELEASE_350/final - FAIL
clang 3.5.1 RELEASE_351/rc2 - FAIL
