A debugging session is active.

    Inferior 1 [process 21807] will be killed.

Quit anyway? (y or n)

The issue seems to be related with contents of ~/Books directory. I've narrowed ~/Books contents to two .fb2.zip files. When these files are both present in ~/Books, I observe above crash when opening a book (with a fresh config; before I run fbreader I rm -r ~/.FBReader directory); when ~/Books contains only one of them, there are no crashes.

geometer commented 11 years ago

Could you please send me the file?

md2 commented 11 years ago

Sent. Subject is "Issue #226". How to reproduce the issue: $ mv ~/Books ~/Books.orig $ mkdir ~/Books $ rm -r ~/.FBReader Copy those two files to ~/Books $ fbreader Now

  1. Press first icon on the toolbar to go to the library.
  2. Open one of the books
  3. Go to the library
  4. Open another book
  5. Repeat from 1.

It takes several iterations for FBReader to crash.

My version of expat is 2.1.0-r2

I've fixed this annoying bug at last, I believe. Here's the patch:

        bookTextView.setContentsModel(0);
        contentsView.setModel(0);
-       myModel.reset();
        myModel = new BookModel(book);
        ZLTextHyphenator::Instance().load(book->language());
        bookTextView.setModel(myModel->bookTextModel(), book);

What happens here? myModel shared pointer resets to null pointer, and next line a new BookModel assigned to it. But in between myModel.reset() and assigning new value to myModel BookNode::highlighted() is called, which calls FBReader::currentBook(), which uses myModel, that is null now.
