It does not matter how this $ORIGIN token is quoted. Perl > always expands it. I've encountered this in build systems before, where the quoting is inconsistent and apparently can result in different levels of dequoting for a target depending upon how it was reached. What I've used for building those has been to specify %ORIGIN instead of $ORIGIN and then binary-edit the resulting binary to switch that % back to a $. All quoting issues disappear and all binary offsets are stable. Just make sure the binary-edit step is before any binary signing. :) At some point, it's also worth considering static linking. -Phil
