The following testcase (due to the dependencies provided as cmake project) illustrates this: -- main.cpp: #include <catch2/generators/catch_generators.hpp> #include <catch2/catch_test_macros.hpp> TEST_CASE("Test") { for (int i= 0; i<1000000; i++) { REQUIRE(1 + 2 == 3); } } -- CMakeList.txt cmake_minimum_required(VERSION 3.5) project(slow_asan) add_compile_options(-fsanitize=address) add_link_options(-fsanitize=address) Include(FetchContent) FetchContent_Declare( Catch2 SYSTEM GIT_REPOSITORY https://github.com/catchorg/Catch2.git GIT_TAG v3.3.0 ) FetchContent_MakeAvailable(Catch2) add_executable(tests main.cpp) target_link_libraries(tests PRIVATE Catch2::Catch2WithMain) --- command cmake -DCMAKE_C_COMPILER=${install_dir}/bin/gcc -DCMAKE_CXX_COMPILER=${install_dir}/bin/g++ -DCMAKE_BUILD_TYPE=Release . && make VERBOSE=1 -j && timeout 10.0s ./tests will take significantly longer than in GCC 12 (compiles at -O3). I have not yet tracked down if the compile hog is a GCC issue or not. ^ permalink raw reply [flat|nested] 6+ messages in thread
