Hi all!

I've run into a strange issue with a global array that is being populated by values that (on the face of it) I can't figure out why.

I'm using strict/warnings, and have used Data::Dumper to find the point where the value of my global array is changing. Basically, I have a global array of hashes, with each key being the "type" of a regular expression (I have multiple regular expressions to run on a certain file type, with each regular expression looking for/at a specific part of the file) . The global array is declared at the top of the script:

my @regexes = ();

In a foreach loop within a subroutine, I make a call to another sub: 

foreach (@regexes){
($fileBodyMatch, $decode ) = checkFileBody ($file, $_->{bodyregex});
}

The array looks fine before this subroutine call. The value of "$decode" is what I'd expect it to be. In the subroutine checkFileBody, I do the following ($filename is the $file value being passed in) : 

open ( DKT, "gunzip -c $filename | ") or die "Can't open pipe to $file
+name\n";

At this point, everything still looks good in Dumper. I then do this:

while (<DKT>){
 my $line =$_;
#process data in here
}

[download]

Even before I have the "my $line" declaration I have a Data Dumper call to print out the contents of @regexes and the @regexes array contains the last line of the file read and nothing else.

At the conclusion of the sub, the net result is that the @regexes array contains the last line of the file as the first element of the array, followed by the previous (valid) contents.

Thank you in advance!
