cc @AndyAyersMS @adamperlin @SingleAccretion in case you run into this. I haven't figured out what's wrong with it yet.

The problem is that genCodeForStoreInd is getting a Contained Addr() so there's no address on the stack for it to store to.

This will be fixed in #124846 - thanks to Single for spotting the bug
