Re: Pack and Unpack are Broken for > 0x7FFF_FFFF (in 5.10.0)

Consider:

 use warnings ;

 sub sp {
   my ($v) = @_ ;

   my $p = pack('U', $v) ;
   my @t = unpack('C*', $p) ;

   printf '\x%04X_%04X: ', ($v >> 16), $v & 0xFFFF ;
   print map sprintf('\x%02X', $_), @t ;
   print "\n" ;
 } ;

...
>  sp(0x7FFF_FFFF) ;

...

v5.8.8 result:

 \x7FFF_FFFD: \xFD\xBF\xBF\xBF\xBF\xBD

...

v5.10.0 result:

 \x7FFF_FFFD: \x7FFFFFFD

I didn't see this in all the clutter of warnings.

I thought 'C' worked on Octets ? Which is what 5.8.8 appears to be doing, but not 5.10.0.
