After having a quick look into the function, the following fragment
caught the eye:
@pLine = split(/\s+::\s+/, $_[0]);
$node = $pLine[3];
The problem is that if @pLine is an array with less that 4 elements,
then $pLine[3] would not exist, and $node would be set to 'undef'.
I'd recommend to change the line
if (exists $nodeSuppress{$node})
to
if (defined($node) && exists $nodeSuppress{$node})
That will verify that we would always do a hash lookup for a key which
is defined, and would avoid the warning message you are seeing.
Hope this helps,
