We are experiencing massive test failures in our smoke-testing of the 
Perl 5 core distribution on FreeBSD-13-CURRENT.  I am filing two 
separate bug tickets for these failures, since one failure appeared long 
before the others.  This is the first of the two tickets.

cpan/Test-Simple/t/Legacy/More.t is repeatedly failing during 
smoke-testing of non-threaded builds on FreeBSD-13.  See, e.g.:

Test failures:
~~ ../cpan/Test-Simple/t/Legacy/More.t ......................... FAILED 
54 Non-zero exit status: 1
   [stdio] -Dcc=clang++ -Duse64bitall
   [stdio] -Dcc=clang++
   [stdio] -Dcc=clang++ DEBUGGING

We only have one regular smoke-testing rig set up for FreeBSD-13, that 
of course being one of Carlos Guevara's rigs.  These failures:

i. Do not seem to occur on threaded builds.

ii. Seem to occur on most, but not all, non-threaded builds.

iii. Appear to have first reported during a smoke-test in, which suggests that the 
failures were introduced in, or shortly before commit  That commit 
is in a deleted branch: smoke-me/khw-vlb.

iv. Both Carlos and I have attempted to reproduce this failure manually 
-- but it only seems to crop up during smoke-testing.

v. Here's the end of the file which is failing:

$ tail cpan/Test-Simple/t/Legacy/More.t

# 53469  is_deeply with regexes
is_deeply( qr/a/, qr/a/, "same regex" );

# These two tests must remain at the end.
is( $@, $Err,               '$@ untouched' );
cmp_ok( $!, '==', $Errno,   '$! untouched' );

Thank you very much.
