This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.7.
-----------------------------------------------------------------
[Please enter your report here]
For at least Perl 5.8.7 on Cygwin, delete()ing an environment variable
does not apparently remove that variable from the environment of a
subprocess. Here is a short repro case:
#!/usr/bin/perl
use strict;
use warnings;
$ENV{SHOULD_NEVER_BE_SEEN} = "hello world";
delete($ENV{SHOULD_NEVER_BE_SEEN});
system("printenv | grep SHOULD_NEVER_BE_SEEN");
On Unix systems this script appropriately prints nothing.
On an up to date Cygwin installation this prints "hello world".
This bug manifested itself as a problem with Test::Harness on Cygwin
Perl. For context, see the e-mail thread around this summary message:
