Hello!

User-defined functions works only when I set Record field alignment option in 'Double word'. If I use Byte or Word, function call give AV error (Delphi, UniDac with source).

You should use implicit compiler directive in LiteCallUni.pas:

Code: Select all

{$A4}

or change record definition as:

Code: Select all

unit LiteCallUni;
...
  pFuncDef3250 = ^TFuncDef3250;
  TFuncDef3250 = packed record
    nArg: i8;             // Number of arguments.  -1 means unlimited */
    padding1: i8;
    padding2: i8;
    padding3: i8;
    funcFlags: u32;       // Some combination of SQLITE_FUNC_* */
    pUserData: IntPtr;    // User data parameter */
  end;

(see option "packed" in the record header, and padding1-padding3 in record definition).

Thank you.

We've reproduced the issue and fixed it. The fix will be included in the new UniDAC build, which we're planning to release next week.
