@steffenlarsen, we already have issue for that fail - #10682.

@steffenlarsen, we already have issue for that fail - #10682.

@bader - I think we can close that one with #13695 since it focuses on opaque pointers. The failure reported here seems to be Gen12 specific and actually relating to alignment

[bader]

No. It's related to opaque pointers support. GPU compiler doesn't handle opaque pointers with Alignment decoration correctly. This is a duplicate of #10682, which is not fully covered by #13695.

Ah, good to know. Thank you for clarifying. Closing this in favor of #10682.
