R coxph() Error: object 'Ccoxmart' not found

I am getting the following error every time I run a Cox model using the survival package in R. This error arose within the last few days. To illustrate the error, I am using a standard example command which is given at https://stat.ethz.ch/R-manual/R-devel/library/survival/html/coxph.html:

# Fit a stratified model, clustered on patients 
library(survival)
bladder1 <- bladder[bladder$enum < 5, ] 
coxph(Surv(stop, event) ~ (rx + size + number) * strata(enum) + 
      cluster(id), bladder1)

The error I get is as follows:

Error in fitter(X, Y, strats, offset, init, control, weights = weights,  : 
  object 'Ccoxmart' not found

I am using latest version of R [3.4.0 (2017-04-21) -- "You Stupid Darkness"].

I have tried to consult the survival package manual for R and researched on the internet. I am grateful for any resource or solution you may recommend.

You have to re-install packages that use C or Fortran in R 3.4.0:

update.packages(checkBuild=TRUE)

See this post

Packages which register native routines for .C or .Fortran need to be re-installed for this version (unless installed with R-devel SVN revision r72375 or later)

I can confirm this error. It's definitely something to do with the update from R 3.3.3 (Another Canoe) -> R 3.4.0 (You Stupid Darkness). All unit tests in my system working correctly on Friday, broken Monday.

In addition, I'm also having an issue with "Ccoxph_wtest" not being found. Must be a similar issue.

I'll start debugging later today and let you know what I find, but for now if you have to get back up and running, I'd suggest reverting to R v3.3.3 (Another Canoe). I have rerun all my unit tests using v3.3.3 and all is fine.

Here is the sessionInfo():

My solution was to re-install the survival package. Just install it right on top of the original. install.packages("survival").
