JCEF #73 detailed-example asserts at exit every time

Postby hmn » Sat May 11, 2019 2:33 am

Hi

The issue: Every time i execute run.bat, and after the google page is fully loaded, i exit the App, then the libcef_dll fails the refcount check every time.

I modified make_distrib.bat a bit to build in debug mode.

Not sure how to file a proper report on it.
i checked in BitBucket for "Check failed: base::AtomicRefCountIsZero" and it has only two reports dd 2016.


The JCEF version i built says in the readme :
Java Chromium Embedded Framework (JCEF) Binary Distribution for Windows 64-bit

Did you modify the example in any way? In README on bitbucket you will find what information you need to provide when submitting issue in the tracker.
