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.
