The problem is indeed the note, but I don't think it comes from it being sort

If it's due to the reported difference using fma and not using fma then
probably the tree fma code lacks checks for debug stmts.

The code that sets the span is never reached. I am studying this to see if I
can sort it out. I think the problem is in trans_decl.c
