V8 on android SIGSEGV fault

[Shailesh Soliwal]

I was successful in building v8 using following command:

make android_arm.release i18nsupport=off 

And integrated with JNI code:

        v8::V8::InitializeICU();

        myplatform = v8::platform::CreateDefaultPlatform();

        v8::V8::InitializePlatform(myplatform);

        v8::V8::Initialize();

        v8Isolates[handle] = new V8Runtime();

        v8Isolates[handle]->isolate = Isolate::New();

        v8Isolates[handle]->isolate_scope = new Isolate::Scope(v8Isolates[handle]->isolate);

I get the following error in my app when i run it in my android emulator:

Checked out stable release version and the problem was resolved:

git checkout tags/4.1.0.21

Still no idea what the issue is though...
