Make a matching fix for numpy/numpy#29811 :
If a malloc fails inside of a gufunc loop, set the Python error state. Otherwise the gufunc sliently returns garbage (an array or zeros or something).
The numpy PR has a way to trigger the problem, itself taken from https://github.com/Quansight/deshaw/issues/603
