To me, these numbers smell of numeric over-/ underflow, or miscasting. In hex, these are: 0xFFFFFFFF91F1A000 0xFFFFFFFFD6839000 So these can either be stack pointers, negative numbers, or bogus 32 bit values. Not sure what Ruby is doing here. -- Sincerely, Stephan Stephan Diestelhorst Staff Engineer ARM R&D Systems -- IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
