Weird--

   I see you're using RH8.  This looks like a UTF8 Locale issue.  RedHat 
8 changed the default encoding to utf8.

  I can easily replicate this on my RH7.3 box when explicitly setting LANG.

  echo 0123456789 0123456789 | LANG=en_US.utf8 perl -lne 'print lc($1) 
while /(\d+)/g'
0123456789
00c06789

I believe this is smarter in perl5.8.1-to-be and 5.9.1-to-be.
