Eigen::eigen_assert_exception missing from includes of src/Core/products/Parallelizer.h and src/Core/CommaInitializer.h

With v3.3.8 released 5Oct2020, I see the following:

external/eigen/Eigen/src/Core/products/Parallelizer.h:162:40: error: no member named 'eigen_assert_exception' in namespace 'Eigen'
  if (errorCount) EIGEN_THROW_X(Eigen::eigen_assert_exception());
                                ~~~~~~~^
external/eigen/Eigen/src/Core/util/Macros.h:1017:34: note: expanded from macro 'EIGEN_THROW_X'
#  define EIGEN_THROW_X(X) throw X
                                 ^
1 error generated.

It appears that this struct is only defined in test/main.h, perhaps it needs to go elsewhere or there was a piece left out of a commit:
