Niels Larson reports that Perl 5.20 compiled with -DPERL_NO_COW has a regression with state variables: they get reset to undef when accessed:
sub no_PERL_NO_COW_regression {
state $s;
$s = 'foo';
my $c = $s;
return defined $s;
}
ok(no_PERL_NO_COW_regression(),
"state variables don't surprisingly disappear when accessed");
Bisection reveals that the bug was introduced in 9ffd39ab75dd662df22fcdafbf7f740838acc898 (between 5.19.6 and 5.19.7), and fixed in c0683843e9299db25f354e2c8c90faa7614950d1 (between 5.21.4 and 5.21.5).
I'm creating this ticket so that (a) a regression test can mention it, and (b) the meta-ticket for 5.20.2 can depend on it.
