App Crashes When Using Different PDFs

This project has great promise, thanks for sharing. I am running into a major issue - the app crashes when I use different PDF's from the sample ones. Here's how to duplicate:

Copy a different PDF into the project (I have trade many PDFs, almost all of them cause the app to crash)
Do a search where you get many results (i.e. search for "t")
Scroll through the table results - the app will crash during the scroll

No error shows in the console, so this has been very hard to debug. I've attached a PDF where this crashes rather easily, but again, it crashes on most PDFs.

    Hi, we are looking into it but it seems the problem is related to the rendering of the table view's cell involving CoreText rather than the search process inside the pdf.

    Yes, I agree, that is where the problem lies. Thanks for looking into this.

    We pushed a small fix on github. A cleaner layout of the code and guarded release of the resources seem to have solved the problem . Probably one of the core text function not returning a valid reference or returning NULL.
    Please provide feedback on this issue.

    I confirm that this is fixed. Thanks so much for getting a fix out there so quick - I am very impressed and very grateful!
