This is a bug report for perl from bulk88@hotmail.com,
generated with the help of perlbug 1.40 running under perl 5.21.4.


-----------------------------------------------------------------
[Please describe your issue here]

See attached patch. I am not 100% sure about this patch, since people 
did report bugs/tickets with these panic messages in the last couple of 
years. The original intent does sound like it should be DEBUGGING code.

Google "panic sv_len_utf8" and "panic utf8_mg_pos_cache_update" for the 
story, "panic sv_pos_b2u" return a couple very old hits too.

[Please do not change anything below this line]
