Attempt to initiate a new Adaptive Server operation with results pending

Hi,
I have program which uses FreeTDS db-lib.dll
Now I have changed TDS version from 7.1 to 7.3 and I start receiving 
"Attempt to initiate a new Adaptive Server operation with results 
pending" in some places.

For example, when I send this two commands:
   "IF @@TRANCOUNT>0 ROLLBACK"
followed by:
   "BEGIN TRANSACTION"

I get above mentioned error.

I attach portion of logs for 7.1 and 7.3 version.

As you can see in both cases is returned : more_results = 1 after "IF 
@@TRANCOUNT>0 ROLLBACK"
(I do not understand why?)

But in case 7.3 is error raised afterward (in 7.1 no error) Is it expected ?
Can you give me some explanation what is going on ?

Thanks
-Laco.
P.S. I resend this email to maillist, because first does not arrive 
there after 3 days
