I don't know if I can sensibly identify where the next stack frame is --- visual inspection leads quicker to sleepyness than anything else. The only thing I've come up with is to add a unique "string" to the top (and/or bottom) of the stack variables. This string could help me find the stack frame (something more "obvious" to look for) ... it's also possible that one could check the string on entry/exit to key vinum functions ... but there is a chance that we're not in the vinum code when things crash.
