I wonder if you could be running into an entry in %ENV with a undef
value?  In that case we could end up with an odd number of
hash-elements and worse.  Perl will ignore the undef values from
hashes "exploded" within parens, e.g. within the ... part of @x = (
... ).  When we come to assign the resulting list back into a new hash
we then get "misalignments".

TIA for clarifying where this suggestion turned out to be wrong or unhelpful :)
