I have a problem with missing captured strings in a script supposed to parse the output of the mysqlbinlog tool: 
my $comment = '^(\/\*.*\*\/\;)(.*)';
[...]
while ($statement !~ m{$comment}s) { $statement .= <$file> or die "Pre
+mature EOF.\n"; }
print "Found type 1 comment: $1\n";

Executing this code always produces: 
Use of uninitialized value in concatenation (.) or string at ./test.pl
+ line 16, <$file> line 1.
Found type 1 comment:

For the line containing the print statement, meaning that $1 is not defined. But I don't understand how that could be. If the regular expression matched there should be something captured, and if not the line wouldn't even be executed...

I tried to reformulate this as while (!($statement =~ m{$comment}s)) but that didn't help either. Could anyone tell me, why nothing's captured here?
