I don't know whether this is part of a larger script, but $refnum never gets set in this snippet, so you are storing your data in a hash entry with an empty key. That's why the entry with key '1' is undefinded undefined, triggering your die.

Perhaps in the while loop you meant:

$names{$ref}=$str;

Update: stop inventing new verbs
