Sorry, should have said this is in 2.14.0.
Using traceback() as you suggested solved this problem for me, thanks. this
made it pretty obvious:
2: checkUnique("\\description")
looks like I typed desc
can point me to what
a minimal .Rd file has in it.
The file is already pretty minimal, so it's possible I've already gone to small
and that is the reason for the error.

v1 <- list(a=x,b=3)
g(x)
v1
}
g <- function(x) {
BFGS type papers tend to be long on the BFGS
explanations and short on the line search explanations. If someone pointed
me to a good line search paper that uses the Wolfe conditions...

Have you considered using the optim function with L-BFGS-B for bounded
optimization. Obviously, you will have to do changes of variables so that
everything is in terms of a rectangle (which is the type of bounding that it
accepts).
I believe it is based on "A LIMITED MEMORY ALGORITHM FOR BOUND CO
