The app is now crashing at InternalFunction which calls jsDynamicCast in JSCast.h, which lead to the initial crash. This assert failure occurs because the type value is ObjectType instead of InternalFunctionType or NullSetterFunctionType. I need to check why this is happens.
NDEBUG and ASSERT_ENABLED are used interchangeably in the WebKit code. So, for creating a build without asserts, you can either use the release build PDBs, or set NDEBUG to 1 in WTF/wtf/PlatformEnable.h to generate a minimal debug build.

Is there any way we could turn off assertions in general when producing debug build?

I’m currently looking into why the native debug build is crashing. This same assert fails while running FileReaderTest using the native debug build. For the time being, you can try building by removing this particular assert statement for debugging.
