Perhaps the bug is w/ Perl itself? I found <https://rt.perl.org/rt3//Public/Bug/Display.html?id=80190>, which includes a small test program. On my computer it outputs:
$ ./zow.pl 1..8 ok 1 ok 2 ok 3 ok 4 ok 5 ok 6 not ok 7 # Failed test at ./zow.pl line 15. # got: '4' # expected: '2' ok 8 # Looks like you failed 1 test of 8. and exits failurefully. What does that program do on your computer? -- Thien-Thi Nguyen ..................................... GPG key: 4C807502 . NB: ttn at glug dot org is not me . . (and has not been since 2007 or so) . .
