+Subject: [PATCH] Add missing return statement in numpy import
+
+This adds a missing return statement in the python3 specific
+import logic of boost.python.numpy.
+
+For python3 wrap_import_array() needs to return a pointer value.
+The import_array() macro only returns NULL in case of error. The
+missing return statement is UB, so the compiler can assume it does
+not happen. This means the compiler can assume the error branch
+is always taken, so import_array must always fail.
