Tests fail (with YAML 1.21?)

[eserte]

The test suite started to fail on my smokers:

#   Failed test at t/02_diff_fully-pp.t line 16.
#     Structures begin differing at:
#          $got->[1] = undef
#     $expected->[1] = ARRAY(0x22d44e0)
# Looks like you failed 1 test of 13.
t/02_diff_fully-pp.t .... 
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/13 subtests 

#   Failed test at t/02_diff_fully.t line 15.
#     Structures begin differing at:
#          $got->[1] = undef
#     $expected->[1] = ARRAY(0x26818b8)
# Looks like you failed 1 test of 13.
t/02_diff_fully.t ....... 
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/13 subtests 

Statistical analysis suggests that the problem happens with YAML 1.21:

I can confirm this issue.
Correction is welcome. :-)

These test failures persist when you attempt to install the library against perl-5.27.10 on FreeBSD-11.0, using cpanm as the installer. Here is date from the build.log:

Other CPAN distributions depend on getting this one installed. We will be unable to assess the perl-5.28-readiness of those distributions until this one is itself perl-5.28-ready.

Thank you very much.

I fix it in my fork: neo1ite@83f67e5

Thanks. When can we expect a new CPAN release?

Thank you very much.
