If I compile your source into my project it crashes with an Assert:

Project PA.exe raised exception class EAssertionFailed with message 'Assertion failure (D:\VCL\UniDAC\Source\MemData.pas, line 8013)'.

To solve the issue, please try to change the code in MemData.pas module:
Code: Select all
TItemHeader = packed record
Block: PBlockHeader;
Prev: PItemHeader;
Next: PItemHeader;
Rollback: PItemHeader;
Status: TItemStatus;
UpdateResult: TUpdateRecAction;
Order,
SavedOrder: integer;
Flag: byte;
FilterResult: TItemFilterState;
end;
to
Code: Select all
TItemHeader = packed record
Block: PBlockHeader;
Prev: PItemHeader;
Next: PItemHeader;
Rollback: PItemHeader;
Status: TItemStatus;
UpdateResult: TUpdateRecAction;
Order,
SavedOrder: integer;
Flag: byte;
FilterResult: TItemFilterState;
{$IFOPT Z+}{$ELSE}
AlignByte: byte; // for align struct size only: SizeOf(TItemHeader) mod 2 = 0
{$ENDIF}
end;

Hello Viktor, thanks but I assume this will be in the upcoming release, so I'll just wait for that. This was only an issue when I needed to send out an app with assertions on for remote client testing.
