So I wonder where exactly we get this non-invariant address from and what makes substitution into regular stmts fixed up? Looks like the substitution is for &<retval> which we deal with separately for regular stmts. I guess we do not share the ADDR_EXPR tree so we can't put a remap of that here. But we may be able to detect this case up in copy_debug_stmt itself? The debug stmt seems to be # DEBUG D#2 => MEM[(double *)&<retval>] and retval maps to D.2566[_9]. And I guess in regular code we never end up with &<retval> anywhere. So not sure how we ended up with that DEBUG stmt in the first place...
