In Numpy, when attempting to perform operations on pairs of arrays of different shapes, Numpy tries to broadcast the arrays to make the shapes compatible. When this is not successful, an exception is raised in Python.
In mojo, no exception is raised and mojo continues execution with a `` pointer.
Steps to reproduce
Here is a minimal example:
from python import Python
defmain():
varnp= Python.import_module("numpy")
x = np.array([1.0, 2.0, 3.0]).reshape(-1, 1)
y = np.array([3.0, 4.0]).reshape(-1, 1)
z = x + y # No exception; z is .print(z.shape) # This statement causes the segmentation fault.
