Hi @merykitty , the problem is that if I verify the results, the bug won't be triggered without `-Xcomp`.
So do you have any idea to reproduce this bug while keeping the verification?

>Also, you could modify the current tests in `jdk/incubator/vector/*VectorTests.java` and `compiler/vectorapi/VectorMaskLoadStoreTest.java` since they are effectively don't do anything regarding compiled codes under normal execution.

This test is actually made from `compiler/vectorapi/VectorMaskLoadStoreTest.java` by removing the results checking logic.
