Hey, guys.
I’m using clang over JNI for syntax highlighting in my Android apps.
It worked great until Android Marshmallow, and now it crashes (Fatal signal 11 (SIGSEGV)) in library loading (System.loadLibrary() in java code).
I was able to get stacktrace:

Any thoughts why it happens?
Is it know bug/feature? Any fix or ideas on how to fix it?
I know Android Marshmallow brings new security model and now permissions should be requested in runtime but what permissions are required in this case?
Regards, Anton.
