Firebird build log
I discovered this bug when I upgraded to 257311 using the official Ubuntu 14.04
nightly packages. After the upgrade, clang would crash in the "Combine
redundant instructions" pass. I was able to bisect this regression down to
257164 with my own builds of clang.
Steps to reproduce:
1. $ git clone git://anongit.freedesktop.org/libreoffice/core
2. $ git checkout libreoffice-5-1 (optional, master fails with same errors)
3. $ apt-get build-dep libreoffice ( also lo_usefull Shell Script if missing
dep)
4. create file autogen.input with CC=clang and CXX=clang++
5 ./autogen.sh && make</pre>
