There were two problems. First, numpy ignored my export

I 'fixed' that problem by adding symlinks in the default directories.

Numexpr is a fast numerical expression evaluator for NumPy. With it,
expressions that operate on arrays (like 3*a+4*b) are accelerated

Works for me. This is exactly the crash that the test tests, so perhaps
you have an incomplete rebuild. I'd try rm -rf build and rebuild.

It turns out that when comparing dtypes, the subarray is currently ignored.
This means you can get things like this:

True
