#N:hp-pcd:34300001:000:304 hp-pcd!jason Dec 12 16:38:00 1983 OS: BSD 4.1 Hardware: Vax 11/750 How can one detect the last routine stackframe? The saved FP (frameptr) of the last stackframe seems to be pointing into an arbitrary stack location. It is not zero. It does not point to a valid routine stackframe. Thanks. -Jay !hplabs!hp-pcd!jason
