[Lazarus] Recent changes in XML?

[Vojtěch Čihák]

Hi,
 
I am not sure if this XML issue belong to Lazarus or FPC.
 
I noticed that my app. gives warning "Constructing a class "TXMLObjectWriter" with abstract method "WriteSignature" and later crashes.
So I tried demo "streamasxmldemo" from lazarus/examples and it is the same: "mainunit.pas(109,52) Warning: Constructing a class "TXMLObjectWriter" with abstract method "WriteSignature""
The demo crashes at startup.
 
The class is in Laz2_XMLCfg but it uses TWriter and TReader from ../rtl/../classes/..
 
TWriter has property Driver: TAbstractObjectWriter which is IMO causes the troubles.
 
I can say that I moved from FPC 30069 to 30494 yesterday and Lazarus from 485xx to 48681, so the changes had to be in this range.
 
I can make a report but tell me at least if it is Lazarus or FPC bug.
 
Thanks, V.
