[Rd] corMatrix crashes with corARMA structure (PR#9952)

[ripley at stats.ox.ac.uk]

This is already fixed in nlme_3.1-86!

> Sigma <- corMatrix(tmp, covariate = 1:n) # segfault
Error in corMatrix.corARMA(tmp, covariate = 1:n) :
   'object' has not been Initialize()d

Please do check that things you report are not already fixed.
