It's the 9th execution of an eval (not an eval on line 9). For example, the script below would give 

Use of uninitialized value in array element at (eval 9) line 4.

#!/usr/bin/perl

use warnings;

my $code_err = q|
my @arr;
my $i;
$arr[$i] = 0;     # line 4 within this code snippet
|;

my $code_ok = q|my $var = ""|;

eval $code_ok for (1..8);
eval $code_err;   # 9th eval, but line 14 in this script
