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);
}
//-----------------------------------------------------------------------------
You're missing a minus sign before the second "tolerant_floor".
