Subject UPDATE Re: [IBO] select view crashes a remote Firebird Server
Author kokok_kokok
Hi Helen

I have sent an e-mail to your e-mail account.


Of course I am interested in the FB 1.5.1. It has been torturing me
for this last year. I am frustrated because I could not give a
response to the customers.

In any case, I am a little sceptical with FB 1.5.1 because I had the
same problem using FB 1.0. Then, when I installed FB 1.5, I believed
that the bug was fixed, everything worked ok and seemingly the
errors had disappeared. The reality is that the bug was hidden and
latent. As you have seen, this bug appears only with a combination
of queries and a specific view. If you modify the view or the
combination of queries, everything works ok.
I mean that the detonating of the bug is not clear, it is very
confused and depends on a lot of factors. Any modification (view,
queries, FB version, ...) can hidde the bug, but the bug exists.

Maybe now this bug has been fixed, I would like to try it. Please,
where I can find the version?

Thank you for your help, now I see a little of light.
