first of all​:

i have not actually verified this bug with perl v5.004.04.

i have verified it on perl v5.005.02 and v5.005.03.

SunOS 5.6, i believe.

"perl -v" on the machine i was using reports​:
This is perl, version 5.005_03 built for sun4-solaris

anyway

here is test program​:

#!/usr/local/bin/perl -w
use strict;
use diagnostics;

#
# this program will print weird warning message
# as part of first filename returned from "glob"
# if any directories above the one given are not
# readable by current user.
#

my $directory = $ARGV[0];
my $file_suffix = $ARGV[1];

print "directory = $directory\n";
print "file_suffix = $file_suffix\n\n";

print "executing chdir $directory...\n";
chdir $directory;
print "chdir executed.\n\n";

print "executing glob...\n";
my @​files = glob ('*' . $file_suffix);
print "glob executed.\n\n";

for my $file (@​files)
{
  print "filename = { $file }\n";
}

print "\n";

exit;

#
# end of test program
#

if i run the program (called tmp.pl) like this​:

perl tmp.pl SOME_DIRECTORY_NAME SOME_FILE_SUFFIX

where i do not have read access to all directories above
SOME_DIRECTORY_NAME then the first filename returned by glob function
will have "Warning​: cannot determine current directory\n" as part of
(specifically, pre-pended to) the name.

To be clear​: It does *not* generate an error or warning.

Rather, the *text* of that warning message is *part* of the first
returned filename.

This seems pretty clearly wrong, ie a bug. It certainly "complicates"
dealing with the filenames returned by glob!

Hope this helps!
Thanks; perl is cool. :)
