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

I recommend that you take this up *first* at Devel-NYTProf's bug tracker at:

https://github.com/timbunce/devel-nytprof/issues

I recommend that because you are testing what is listed as a *development* version of this library (see: http://search.cpan.org/~timb/Devel-NYTProf-5.06/).

Since the latest *official* release of Devel-NYTProf has been passing most, but not all, of its smoke tests against Perl 5.20.0 and later (see: http://matrix.cpantesters.org/?dist=Devel-NYTProf+5.06), we have to rule out a bug in Devel-NYTProf before considering a bug in Perl itself.

Thank you very much.

Using Devel-NYTProf-5.06_80 and perl 5.20.0 compiled

I recommend that you take this up *first* at Devel-NYTProf's
bug tracker at:
https://github.com/timbunce/devel-nytprof/issues

Done:
timbunce/devel-nytprof#38
"use_db_sub=1 triggers perl assert abort: function Perl_rpeep, file
op.c"

I recommend that because you are testing what is listed as a
*development* version of this library (see:
http://search.cpan.org/~timb/Devel-NYTProf-5.06/).

Same happens with Devel-NYTProf-5.06 as with Devel-NYTProf-5.06_80,
also aborts with perl-blead 5.21.4 (just a different line number).

Since the latest *official* release of Devel-NYTProf has been passing
most, but not all, of its smoke tests against Perl 5.20.0 and later
(see: http://matrix.cpantesters.org/?dist=Devel-NYTProf+5.06), we have
to rule out a bug in Devel-NYTProf before considering a bug in Perl
itself.

Sure, thank you for a prompt response.

This looks like a perl bug rather than a Devel::NYTProf problem.

Here's a pure-perl reproducer:

perl -d -e 'BEGIN { $^P &= ~0x4 } sort { $$b <=> $$a } ()'

0x4 is PERLDBf_NOOPT.

Per timbunce/devel-nytprof#38 this appears related to 932bca2 (but I've not actually done a bisect).

I have done a bisect, and it is that commit. I also have a local fix, but I may not push it until later today, or even tomorrow, as I also have other local changes that break things.

This is now fixed in 4c62787. This should be a candidate for maint-5.20.
