There appears to be an issue with the blocks in the code. I don't know if this is related to Test::Harness alone, or if this is a Cygwin Perl bug. I added the following line to the end of the block called "PROVE_SWITCHES" and it worked just fine. undef $ENV{PROVE_SWITCHES};

Can you please try the following program under Cygwin for me: #!/usr/bin/perl -w use warnings; use strict; my $key = "WANGO"; BLOCK1: { my $val = $ENV{$key}; $val = "undef" unless defined $val; print "In BLOCK1, \$ENV{$key} = [$val]\n"; } BLOCK2: { local $ENV{$key} = "FOTANGO"; my $val = $ENV{$key}; $val = "undef" unless defined $val; print "In BLOCK2, \$ENV{$key} = [$val]\n"; } BLOCK3: { my $val = $ENV{$key}; $val = "undef" unless defined $val; print "In BLOCK3, \$ENV{$key} = [$val]\n"; print " ... BUT IT SHOULD BE undef!" unless $val eq "undef"; } === cut === The output I get is: In BLOCK1, $ENV{WANGO} = [undef] In BLOCK2, $ENV{WANGO} = [FOTANGO] In BLOCK3, $ENV{WANGO} = [undef] What do you get? xoa -- Andy Lester => andy@petdance.com => www.petdance.com => AIM:petdance

Well, I'm confused. I got what we expected... $ ./test.pl In BLOCK1, $ENV{WANGO} = [undef] In BLOCK2, $ENV{WANGO} = [FOTANGO] In BLOCK3, $ENV{WANGO} = [undef]

OK, I tried something similar to what is above, but made some changes to make it more similar to the actual test. #!/usr/bin/perl -w use warnings; use strict; my $key = "WANGO"; BLOCK1: { my $val = $ENV{$key}; $val = "undef" unless defined $val; print "In BLOCK1, \$ENV{$key} = [$val]\n"; } BLOCK2: { local $ENV{$key} = "FOTANGO"; my $val = $ENV{$key}; $val = "undef" unless defined $val; print "In BLOCK2, \$ENV{$key} = [$val]\n"; } BLOCK3: { my $val = qx/test2.pl/; $val = "undef" unless defined $val; print "In BLOCK3, \$ENV{$key} = [$val]\n"; print " ... BUT IT SHOULD BE undef!" unless $val eq "undef"; } =cut test2.pl #!/usr/bin/perl -w use strict; my $val = $ENV{WANGO}; $val = "undef" if ! defined $val; print $val; =cut Now, my results on Cygwin are... In BLOCK1, $ENV{WANGO} = [undef] In BLOCK2, $ENV{WANGO} = [FOTANGO] In BLOCK3, $ENV{WANGO} = [FOTANGO] ... BUT IT SHOULD BE undef! On Linux (Perl 5.8.2 on Gentoo with a 2.4.26 kernel) are... In BLOCK1, $ENV{WANGO} = [undef] In BLOCK2, $ENV{WANGO} = [FOTANGO] In BLOCK3, $ENV{WANGO} = [undef] I tested this out on Win32(Perl 5.8.3) and HP-UX (Perl 5.8.3) also, and it behaves as expected. My guess is that this is a Cygwin issue rather than a Perl one, but I'd have to dig a bit more to be sure. This might be a good P5P question.
Added a fudge of $ENV{PROVE_SWITCHES} for Cygwin only.
