@atrick Could this be useful? I'm not sure if this duplicates the tests in #78482.

[atrick]

Thanks. We did already have a source level test for the fix, but this test exhibits the compiler crash rather than just checking the SIL output. So it may have some value.

Would it not be better to put this in validation-test/SILOptimizer?

[hjyamauchi]

@AnthonyLatsis I think any place that's run for each pre-submit PR would be good. Does the pre-submit PR CI run validation-test/SILOptimizer?

[AnthonyLatsis]

Your test will definitely run. Some tests in the validation suite are not normally run, but this is due to metaprogrammed requirements in them rather than their location. I think we should avoid using test/Misc as a dumping ground any further. We need to distribute those tests to dedicated folders and delete it.

@swift-ci please test

Moved the test to validation-test/SILOptimizer. PTAL. @AnthonyLatsis
