[c-nsp] "sh run" crashes router

[Richey]

I am setting up Tacacs+ on all of our far end routers so I can run rancid.
I have found several 1720s and a 2621 that crash when I log in to them and
issue the "sh run" command.   They reboot quickly and then I don't have a
problem with the "sh run" command after the reload.   If I look at the
output from a "sh ver" I get  System returned to ROM by error - a SegV
exception, PC 0x8066A150.    This seems to only be a small number of
routers.  They are in different environments (one is in a server room,
another on the wall in a warehouse, etc)   The 1700s are running various
versions of the same image type.    The only thing that they all have in
common is that it's been months since anyone has logged into the router.
Is this some bug that comes from long uptimes without any activity at the
CLI?
