A typical instance looks like follows

hMetaData->ind_list[indice_coherence + i].value = ( idx & ( ( 1 << k ) - 1 ) );

I do not see an obvious arithmetic problem here, but I think that the assignment should be at least rewritten to BASOP instructions.

@pihlajakuja, who could be the best assignee, please?
