[ID 20000307.008] each on hash-in-place loops infinitely
Message ID:

This is a bug report for perl from peter@psdt.com,
generated with the help of perlbug 1.27 running under perl v5.5.650.

-----------------------------------------------------------------
[Please enter your report here]

If keys and values work okay on a hash defined with a block as the
variable name, one might expect each() to also.  Instead it gets
into an infinite loop (it prints a different pair on Solaris 5.005_03,
FWIW).

use strict;
print keys %{{abc => 123, def => 456, ghi => 789}};
print values %{{abc => 123, def => 456, ghi => 789}};
while (my ($k, $v) = each %{{abc => 123, def => 456, ghi => 789}}) {
  print "$k $v\n";
}

abc 123
