Can you please print out at this point:
V217
V218
V216
LnkLI169
For the variables, if non-null, you should also be able to
p pp(V217)
etc., or
p V217->d
p V217->c if cons, etc.
My guess is that LnkLI169 has been faslinked to a bad place. Once you
know its value, perhaps you can search for the appropriate
call_or_link in your make log output, break there and investigate.
Take care,
