Threading

I have build dds with openmp threading. Now when I build tenace and start it, I get:

 matica!156 tenace-0.16$ OMP_NUM_THREADS=4 ./src/tenace 
Memory::GetPtr: 0 vs. 0

The message clearly comes from dds, because it is written in C++, unlike tenace. I looked at dds source and the message means that the number of threads for dds is 0.
As you see this happens with tenace 0.16 (dds 2.9.0), and even if I set the overriding OMP environment variable.
