clang 3.5 fails to build searchtest.cpp from the 1.13 branch head:

Reproducible: Always

Steps to Reproduce:
1. checkout akonadi git c733429f
2. cmake -DCMAKE_CXX_COMPILER=clang (etc)
3. make

Expected Results:  
no errors

This error exists only in searchtest.cpp; tested both on OS X 10.9 and KUbuntu 14.04 with clang 3.5 .
