Run the supplied mlir-opt --map-memref-spirv-storage-class reproducer first, then inspect mapMemorySpaceToVulkanStorageClass in MapMemRefStorageClassPass.cpp and the IntegerAttr assertion in BuiltinAttributes.cpp. Determine how the ui64 memory-space attribute is handled, and consider the issue complete when the reproducer no longer aborts and regression coverage protects that behavior.
