co19/TypeSystem/inference/function_literal_inference_A01_t05 now RTE instead of Crash on vm-modaot-mac-debug-arm64 #64485

Open

Description

@sstrickl

There are new test failures on [vm,dyn_modules] Handle re-resolving implicit closures after reload..

The tests

co19/TypeSystem/inference/function_literal_inference_A01_t05 RuntimeError (expected Pass)
co19/TypeSystem/inference/function_literal_inference_A01_t05 RuntimeError (expected Pass)

are failing on configurations

vm-modaot-mac-debug-arm64

This test changes from Crash to RTE in the trybot runs on CL 558860, so preemptively making an issue for this pre-submission.

Log:

/==================================================================================================================\
| co19/TypeSystem/inference/function_literal_inference_A01_t05 failed again (Crash -> RuntimeError, expected Pass) |
