Duncan that does indeed look to be the case. Many thanks!

In particular, tests/reg-tests-1d.R optionally loads the Matrix 
namespace which allows the test to succeed. Compare:

    ~/R-rc_2019-04-21_r76409/bin/Rscript -e "options(warn=2);
    library(Matrix); res <- findMethods('isSymmetric'); print('success')"
    [1] "success"

versus

    ~/R-rc_2019-04-21_r76409/bin/Rscript -e "options(warn=2); res <-
    findMethods('isSymmetric'); print('success')"
    Error in findMethods("isSymmetric") :
     ? (converted from warning) non-generic function 'isSymmetric' given
    to findMethods()
    Execution halted
