New bug in 7.1.4 TMemData.ApplyUpdates

[Justmade]

In Line 7205 it write,

Code: Select all

      if OldCurrentItem.Flag = flUsed then
        CurrentItem := OldCurrentItem;

However, the OldCurrentItem, which can be nil, will cause AV exception and halt the apply update.

The old version do not have the if line.

I myself had changed the code to below to prevent the exception.

Code: Select all

      if (OldCurrentItem = nil) or (OldCurrentItem.Flag = flUsed) then
        CurrentItem := OldCurrentItem;

Just for your reference.
