This is a bug report for perl from Mark.Martinec@ijs.si,
generated with the help of perlbug 1.40 running under perl 5.20.0.


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

Not sure if the culprit is Devel::NYTProf, or perl 5.20.0 itself.

Using Devel-NYTProf-5.06_80 and perl 5.20.0 compiled
with -DDEBUGGING, one of the Devel-NYTProf self-tests
causes perl to abort on assertion failure:

$ prove t/test25-strevalb.t
  Assertion failed: ((kid->op_type == OP_NULL && kid->op_targ == OP_NEXTSTATE)
    || kid->op_type == OP_STUB || kid->op_type == OP_ENTER),
  function Perl_rpeep, file op.c, line 12011.
Exit status 6 from /usr/local/bin/perl5.20.0 -d:NYTProf
  at t/test25-strevalb.t line 23.

Same with just the offending line from test25-strevalb.t :

$ NYTPROF='use_db_sub=1' perl -d:NYTProf -e 'use Benchmark'
  Assertion failed: ((kid->op_type == OP_NULL && kid->op_targ == OP_NEXTSTATE)
    || kid->op_type == OP_STUB || kid->op_type == OP_ENTER),
  function Perl_rpeep, file op.c, line 12011.
Abort trap

(wrapped for clarity)
