Potential duplicate of #120085 (same assertion failure, getType(Base)->isPointerType() || getType(Base)->isArrayType()), which has a test case

A couple of other reports of the same assertion failure: #50214, #69468

Can you attach a code example (or Compiler Explorer link) so we can reproduce the issue?

replied above, please have a look.

Unfortunately, that's not a complete reproducer (unless there's an attachment somewhere I'm not able to spot). We need the original source code (or preprocessed output from it), if possible.
