[CLucene-dev] crash -- R6025 pure virtual function call

[Michael Z. (B. 7. LEXIN) <mzh...@bl...>]

I try to write a test application in Microsoft VS 2010 as following. 
and when I debug the code, it crash at:
    writer.addDocument(&doc);
and I get an error message, it shows:
Runtime Error!

Program: C:...

R6025

- pure virtual function call

Anybody knows how to fix it?
Thanks.
