I've been using TT under Windows for some years and can't confirm
this. Could you give a complete example?

You are not by any chance talking about a message like the following?
Odd number of elements in hash assignment at a.pl line 8.
There is nothing wrong with having an odd number of keys in a hash,
neither in Perl nor in TT.
The "Odd number" in the message above means that you have a wrong
initialisation of your hash like e.g.
%HASH = ('key1' => 'value1'
,'key2' => 'value2'
,'key3');
OK, this is easy to spot. However, I recall a case where it took me
some time to figure out what happened:
%HASH = ('key1' => somefunction('value1')
,'key2' => 'value2'
,'key3' => 'value3');
In this case somefunction() is evaluated in list context. If, for
some reason, somefunction() returns an empty list if called in list
context, or a list of two elements, then you get an "Odd number of
elements". As a consequence, 'key2' is being seen as a value, and
'value2' is the key for 'key3' and so on (keep in mind that '=>' is
just an alias for ','). Exchanging keys and values can of course make
TT choke.
