We had problems with FORCE setting on 901x. The query it was changing to bind variables was

select to_char(sysdate,:b1)
from dual
/

Now :b1 is a format mask supplied by developer. Initially it would work fine and then start throwing ORA-600. After analysis Oracle found that when first time a format mask was supplied, it allocated enough bytes to hold the value of the format mask e.g. 'MMDDYY', but next time if you used 'MMDDYYYY' it occasionally threw a fit, saying it can't fit 'MMDDYYYY' in space for 'MMDDYY', which makes sense, but it was actually an memory allocation problem.

I think we received a patch to resolve that issue. It is so old, I can't even look it up in our TAR list. I don't know about the 8i part of it though.
