OverbyteIcsLIBEAY : EAccessViolation

[AndreL 0]

Hi,

Error stack (madExcept) - Delphi 11.3 :

exception class    : EAccessViolation
exception message  : Violation d'accès à l'adresse 77DB3D25 dans le module 'ntdll.dll'. Ecriture de l'adresse 00000008.

main thread ($6450):

008ac3fe +006 xx.System.Classes                                   TDataModule.Destroy

How to reproduce  :

- Application xx is starting from local windows apps store.

- if a newer local version is available then the following code is executed, generating the error:

 

application.ProcessMessages;
ShellExecute(0, nil, PChar(LocalExe), nil, nil, SW_SHOWNORMAL);
application.Terminate;

 

Normal execution is ending properly.

Any help is welcome.

Please provide the exact line in the source code where the exception occurs.

"Ecriture de l'adresse 00000008. " usually means accessing a object using (Item at offset 8 in the object's data) a nil reference.

Far too little useful information to make any proper comment.
