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: ``` ~/r/eigen ((3.3.8))> rg eigen_assert_exception test/main.h 178: struct eigen_assert_exception 180: eigen_assert_exception(void) {} 181: ~eigen_assert_exception() { Eigen::no_more_assert = false; } 213: EIGEN_THROW_X(Eigen::eigen_assert_exception()); \ 233: } catch (Eigen::eigen_assert_exception) { \ 250: EIGEN_THROW_X(Eigen::eigen_assert_exception()); \ 261: catch (Eigen::eigen_assert_exception&) { VERIFY(true); } \ Eigen/src/Core/CommaInitializer.h 103: EIGEN_EXCEPTION_SPEC(Eigen::eigen_assert_exception) Eigen/src/Core/products/Parallelizer.h 162: if (errorCount) EIGEN_THROW_X(Eigen::eigen_assert_exception()); ```
