Weird SQL error in 8.1.6

We are in the middle of testing of upgrading from Oracle 8.0.5.1 to 8.1.6.2 My technical team has come up with an interesting error that Oracle Support seems unable to reproduce or answer. We have a vendor package that generates SQL code and then submits it. Below is an example of the code we are having problems with. The code will run in 8.0.5.1 but not in 8.1.6.1 We are running AIX 4.3.3

select sysdate from dual where '1' = '1'and '2' ='2' /

• notice that there is no space between '1'and **********

Anybody ever see this behaviour or can you recreate on your system.
