Internet Explorer or .NET Application Hosting Web Browser May Crash with Exception 0xE06D7363

This month looks little unusual as I ran into another bug in Internet Explorer component. Jscript9.dll is a core dll for implementing JavaScript engine (aka Chakra engine). The process may crash with C++ Exception code E06D7363. Here are some of the details that may help you. If you have a dump file, then you may use WinDbg (ships with Debugging Tools for Windows) to analyze it.

  1. The KB article has additional details about the bug

    Internet Explorer 9 may crash because of jscript9.dll stack overflow when you browse certain webpages

  2. You may want to install the latest IE security update released few days back. A lot of times, the testing time may not be affected by the patch, you may be better off installing latest patch. Since patches are cumulative, it will give you additional fixes on top of existing fix.

  3. If you see issues even after installing latest patch, then it is possible that more than one condition is contributing to the issue.
  4. Make sure you also install KB3076895 and test it. We had seen issues in GWIM environment because of it.
