title: Can "Attempt to free unreferenced scalar" errors be safely ignored?
body: <p>I haven't figured out what's causing it, but I'm wondering if there are any consequences to the error (warning?) message "Attempt to free unreferenced scalar: SV 0x825b790 during global destruction". To the untrained eye, it would appear that since the compiler bothered to detect the problem, then it didn't go ahead and re-delete the unreferenced memory. </p>
  
  <p>Is this just telling me that my programming is sloppy? or are there real problems happening that I should be concerned about?</p>
  
  <p>Background: it's not my code, I don't really have time to hunt down the problem, and I should note it's happening right at the end of the program.</p>
