* Verify RegisterProfilerManager doesn't overwrite an existing registration Tested: Add a second registration to test/profiler_manager_test.cc and verify the test crashes as expected. * Verify RegisterProfilerManager doesn't overwrite an existing registration Tested: Configure with: cmake -GNinja -DCMAKE_BUILD_TYPE=Debug -DBENCHMARK_DOWNLOAD_DEPENDENCIES=on Then run: ctest -R profiler_manager_gtest Before change test fails (expected), after change test passes (expected) --------- Co-authored-by: dominic <510002+dmah42@users.noreply.github.com>
