If I run the program attached, 132834-Config.pl, as follows​:

#####
bleadperl 132834-Config.pl 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.

As this is a BBC --- should it be a blocker ticket for 5.28?

From @arc

Thanks for the report. This is resolved by 8e4ae0f, which should be part of 5.27.10.
