I can no longer duplicate this:

$ perl6 --version
This is Rakudo version 2016.08.1 built on MoarVM version 2016.08
implementing Perl 6.c.
$  perl6 -e'say "hello".comb(/:m <[o]>/)'
(o)

Closable with tests.

Please, note more information is available with —ll-exception.  For bug 
reporting / triage, this can be very helpful.

Seems to happen somewhere deep in the NQP regex bowels.

$ 6l '"hello".comb(/:m <[o]>/)'
chr codepoint cannot be negative
   at :1  (::73)
 from gen/moar/stage2/QRegex.nqp:1337  
(/Users/liz/Github/rakudo.moar/install/share/nqp/lib/QRegex.moarvm:!cursor_more:97)

 from gen/moar/m-CORE.setting:12519

I haven’t been able to golf this further yet.
