Here is the code as written in my main project followed by a code snippet that I have tried running outside of the project to reproduce the error.

In the code snippet I cannot see a call to getEffectiveRights(@args) as stated in your first code block. How do both pieces relate?

Ah, it is about Win32::Security::Raw::GetNamedSecurityInfo. You should dump the contents of @_ in sub getEffectiveRights - just to be sure the right parameters are passed. Output/logs from both would be helpful, too, in order to help you.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
