It got broken in r939. The problem is in Cell.icc: //----------------------------------------------------------------------------- inline bool Cell::integral_within(APL_Complex A, APL_Float B) { const APL_Complex C = -A; return tolerant_floor(C, B) == tolerant_floor(A, B); } //-----------------------------------------------------------------------------
