Description:
------------
Since some days the snapshot-builds from source under fedora 7 does produce a white page with HTTP-Status 500 and without any messages in logfiles.

I have built it every second day and now it will not run, the cli semms to work normal

If i use the 5.2.3-sources with the same build--script all works perfect

Reproduce code:
---------------
export CFLAGS="-O3 -march=i686 -mcpu=i686 -mtune=i686 -mmmx -msse3 -fopenmp"
export CXX=gcc
export CXXFLAGS="-O3 -march=i686 -mcpu=i686 -mtune=i686 -mmmx -msse3 -fopenmp"
export PHP_PREFIX="/usr"

# In den Source-Folder wechseln
cd /data/development/src/php/

# Config-Cache falls vorhanden entfernen und aufr?umen um Probleme zu vermeiden
rm -f ./config.cache > /dev/null
make clean > /dev/null
