Description
(issue reported by christoph.goettschkes@microdoc.com)
oop::register_oop() is only used in fastdebug builds for the CheckUnhandledOops feature. The assert requires the PC of the current frame to be non-zero. In 32-bit ARM, this is only true if the VM is not compiled in thumb mode. In thumb mode, os::current_frame() always returns a default frame, in which the PC (and every other field) is zero.
