¯\_(ツ)_/¯

When I look at the log I only see as relevant this tail part at the end:

  autopkgtest [21:58:17]: test pkg-r-autopkgtest: -----------------------]
  pkg-r-autopkgtest    PASS
  autopkgtest [21:58:17]: test pkg-r-autopkgtest:  - - - - - - - - - - results - - - - - - - - - -
  autopkgtest [21:58:17]: @@@@@@@@@@@@@@@@@@@@ summary
  run-unit-test        FAIL non-zero exit status 1
  pkg-r-autopkgtest    PASS

which shows no influence of Matrix. Matrix is a core R package (part of the
"recommended" set) and has been there since forever. This is a bug in
glmmTMB.  All the 'gradient function must ...' errors are from its tests and
points to me to a recent change in R (where boolean comparisons can now check
if the compared vector is corre.  The Matrix change may simply be the trigger.

In any event, all these errors also have backtrace:

-- 1. Error (test-VarCorr.R:11:1): (code run outside of `test_that()`) ---------
Error: gradient function must return a numeric vector of length 6
Backtrace:
 1. glmmTMB::glmmTMB(distance ~ age + (age | Subject), data = Orthodont) test-VarCorr.R:11:0
 2. glmmTMB::fitTMB(TMBStruc)
 4. glmmTMB:::optfun()
 6. base::with.default(...)
 7. [ base::eval(...) ] with 1 more call

No Matrix here.

Can you please talk to glmmTMB?  Their GH seems active
(https://github.com/glmmTMB/glmmTMB/commits/master)
