+Subject: [PATCH] Remove error counting in OpenMP parallelize_gemm
+
+This resolves a compilation error associated with
+Eigen::eigen_assert_exception. It also eliminates the counting of
+exceptions that may occur in the OpenMP parallel section. If an
+unhandled exception occurs in this section, the behavior is non-conforming
+according to the OpenMP specification.
