Hi,
I just tested that same code under Windows 2000 and I don't have any
errors or duplicates. As I would have expected. So there seems to be
a bug in the CreateGUID implementation of Linux.
BTW:
I'm using Ubuntu 7.10. My 'uname -a' output:

Hi,
I'm trying to do performance testing in Firebird RDBMS using GUID's
and primary keys. I constantly got PK violations. I then wrote the
code show below to create 50,000 GUID's and add them to a StringList
(no duplicates allowed). Every time

The default implementation on Linux uses a random() call to generate a

Note that random() will always return the same sequence if you don't

You can use the kernel mechanism by inluding libuuid in your uses clause.
That should ensure uniqueness.
Yup, that

Sorry. Openssl has *nothing* to do with the CreateGUID function.

GUID's are supposed to be very unique! Wikipedia says something like:
Create a billion every second for 10 years or something before you
deplete the range.
So what is wrong with my code or maybe the Free Pascal implementation?
I quicktested the FreeBSD implementation, verified it used the

Here you go. It is pretty much what I sent before, except now I made
