Index error in handling of crashed worker

Fatal Python error: Floating point exception

I think this is related to xdist due to these lines:

Start by reproducing the worker crash with pytest-xdist and the compiled-module test at tests/epyccel/recognised_functions/test_numpy_funcs.py, especially test_shape_indexed. Read the worker path shown in xdist/remote.py and compare the node-down handling with the expected E output. Done means a crashed worker is reported without the index error and the regression is covered by a test.
