[SciPy-dev] PyArray_CanCastSafely(exact,inexact) on 64-bit

Hi Travis, Number of scipy.test failures occuring on 64-bit systems are due to the fact that PyArray_CanCastSafely(PyArray_LONG,PyArray_DOUBLE) returns true. Though sizeof(long)==sizeof(double) holds on 64-bit machines, shouldn't PyArray_CanCastSafely return false on (exact,inexact) arguments and vice versa? By the definition of can_cast, no bitwise information is lost, but it is not meaningful to pass (double*)(<pointer to long array>) to a numeric function, for example. Or may be I should use some different function than PyArray_CanCastSafely in this situation? Pearu
