If I run the program attached,, as follows: ##### bleadperl 2> blead-config ##### ... (where bleadperl is v5.27.9 (v5.27.8-154-g4bfb553)), and then grep the output file as follows, I get: ##### $ !634 grep -n -E '^i_(time|stdlib)' blead-config 799:i_stdlib define 800:i_stdlib define 834:i_time define 835:i_time define ##### So it appears that at blead we're getting duplicate elements in %Config! That would explain the test failure and point to an error in blead. Thank you very much. -- James E Keenan (

#!/usr/bin/env perl use 5.12.0; use warnings; use Config; say STDOUT "count: ", scalar keys %Config; for my $k (sort keys %Config) { printf STDERR "%-30s%s\n" => ($k, $Config{$k} // 'undefined'); }
