This is in the Embarcadero documentation.
In the previous links were discussed what to pay attention to.

Apropos ASLR in 32-bit mode: "...Note: {$HIGHENTROPYVA} is only available for 64-bit Windows. Default {$HIGHENTROPYVA ON} Delphi 11.2 expands ASLR support for the Win64 platform. It adds the ability to randomize memory addresses at high locations. This makes 64-bit applications really take adva...

Hi, aehimself, I see you didn't fully understand what the ASLR error is. It is revealed in Win64 mode due to not quite correct use of types (which work properly in Win32). A number of libraries in recent months had to be corrected (released version take into account ASLR inclusion in Win64) that pre...

Hi MFJShark,

Have you checked if your errors persist after disabling ASLR and rebuilding the entire ZEOS and application?

Michal

I think I found the AV reason for Delphi 11.1 sp1 Win64. When ASLR is disabled, the error does not occur. Here's more about it: https://blogs.embarcadero.com/rad-studio-11-1-and-windows-pe-security-flags/ https://en.delphipraxis.net/topic/6627-legacy-bad-code-issues-on-delphi-111-on-64bit-vcl-apps-r...

I think that memory alignments could be a source of problems. As far as I remember, records were always packed in 32 bit C / C++ while they are aligned to some degree in 64 bit C / C++. At least on Windows? It seems that in Delphi 11.1sp1 the issue of align for Win64 has been changed significantly....

That's not the point.
Try to test the same in Delphi 10.3(Win64), 10.4(Win64) or 11.1(Win64) without update1 (if you can).

Hi,

Which version of Delphi?
It seems to me that there is a bug in Delphi11.1 upd1 Win64 that wasn't there before.

ZEOS can be used in three modes: autocommit, explicit transactions and cacheupdate.

Unfortunately, Zeos7.2 and Zeos8 share many namespaces and cannot reside together.
But you can keep each of them in the Zeos72 and Zeos8 directories and for use rename one of them to Zeos
and rebuild the library(dpk group) before use.
