 Not as simple as the section stack would have to be traversed to check
whether there are any differences.  And in the end, either such a complete
check or a simple one you have proposed may not be desirable, because I
can imagine in some scenarios the change of a section in an asm may be
deliberate.  Let's not limit the tools.
