[Rd] R-devel (rev 76409) fails 'make check': non-generic function 'isSymmetric' given to findMethods()

[Benjamin Tyner]

Hello,

Most likely I'm doing something wrong, but am at a loss as to what the 
issue is. I have a clean checkout of trunk here:

    ~/svn/r-devel/R$ svn info
    Path: .
    Working Copy Root Path: /home/btyner/svn/r-devel/R
    URL: https://svn.r-project.org/R/trunk
    Relative URL: ^/trunk
    Repository Root: https://svn.r-project.org/R
    Repository UUID: 00db46b3-68df-0310-9c12-caf00c1e9a41
    Revision: 76409
    Node Kind: directory
    Schedule: normal
    Last Changed Author: ripley
    Last Changed Rev: 76409
    Last Changed Date: 2019-04-21 06:32:24 -0400 (Sun, 21 Apr 2019)

I then ran:

    mkdir ~/svn/R-devel-build
    cd ~/svn/R-devel-build
    ../r-devel/R/configure --prefix=/home/btyner/R-76409 
--enable-R-shlib --with-blas --with-lapack --with-readline 
--without-recommended-packages
    make
    make check

which fails at reg-tests-1d.R; the failure being:

    > ## str() now even works with invalid objects:
    > moS <- mo <- findMethods("isSymmetric")
    Error in findMethods("isSymmetric") :
      (converted from warning) non-generic function 'isSymmetric' given 
to findMethods()
    Execution halted

I am able to build revision 76407 from source just fine (using 
https://cran.r-project.org/src/base-prerelease/R-devel_2019-04-20_r76407.tar.gz) 
and all make check tests are successful.

Any ideas? Here is my sessionInfo() from the revision 76407 build:
