   @Lunderberg Thanks for finding the simple test case! I hit this error when running this Hexagon test https://github.com/apache/tvm/blob/b29ab5c6baea8884a5b9c0702c1c93da6a830866/tests/python/contrib/test_hexagon/metaschedule_e2e/test_resnet50_int8.py#L397. The original test case in this PR, with its `cache_read`, index map etc, was directly taken from this Hexagon test.
   
   The bug is triggered when we hit the code path https://github.com/apache/tvm/blob/b6fae9b35eff4ad1f7cc2e83d8d7da5d701d8e44/src/tir/schedule/primitive/layout_transformation.cc#L282
   
   I was not sure what makes this code path hit and why existing tests didn't hit it.
