The perldiag documentation describes this fatal error as follows:

You used an array where a hash was expected, but the array has no info
+rmation on how to map from keys to array indices.  You can do that on
+ly with arrays that have a hash reference at index 0.

Google returns a number of pages that reference a range of scenarios which generate this error message, most often referring to errors in dereferencing.

As such, more information is really needed to sort this error out, namely, the specific line where this error is occurring and the surrounding code which contributes to values used within the hash assignment on that line.

 

perl -le 'print+unpack("N",pack("B32","00000000000000000000001000100101"))'
