Comment (by bgamari):

 The problem appears to be the encoding of the string literal itself in the
 object code. Previously we would find this,
 {{{
                                                 starts here
 0531220   -   b   o   o   t   -   8   .   3  \0 300 200   g   h   c   p
 0531240   k   g 300 200  \0   d   b   M   o   d   u   l   e   U   n   i
                          ^ ends here
 }}}
 Now we find this,
 {{{
                                         starts here
 0534520   o   o   t   -   8   .   3  \0 303 200 200   g   h   c   p   k
 0534540   g 303 200 200  \0   d   b   M   o   d   u   l   e   U   n   i
                          ^ ends here
 }}}
