Where is the difference?  You can use objdump to determine if it's
in the symbol table, debug section, text, data, headers, etc.

Very few comparison failures are innocuous.

You might look at alias.c from the mainline sources.  Mark has installed
at least one fix in the mainline to fix a bug which cropped up when we
enabled strict-aliasing in the mainline.
