--------------------
As you can see it reaches line 116 and 126 and overlay1,overlay2 and
song seems to be undefined at these lines. You can also see that it
does not reaches line 80, which also seems logical since it will go
into the "if" and not into the "else".
I think the problem is the intialization at line 64, today it looks
like
Code:
--------------------
my ( $line1, $overlay1, $line2, $overlay2 ) = '';
--------------------
If I change line 64 to this instead everything works
Code:
--------------------
my $line1 = '';my $overlay1='';my $line2='';my $overlay2='';
--------------------
I thought your code should work, but I am not a perl expert. Maybe
there is different behaviour in different implementations that causes
this, which also could explain why you couldn't reproduce it. I am
running Ubunut Dapper and the standard perl installation, perl
--version gives:
"This is perl, v5.8.7 built for i486-linux-gnu-thread-multi"
