    Description

      The error message seen when building on macOS on arm64 (sometimes called aarch64) is:

      src/third_party/catch/include/catch.hpp:8122:13: error: invalid token in expression
                  CATCH_BREAK_INTO_DEBUGGER();
                  ^
      src/third_party/catch/include/catch.hpp:7834:79: note: expanded from macro 'CATCH_BREAK_INTO_DEBUGGER'
          #define CATCH_BREAK_INTO_DEBUGGER() []{ if( Catch::isDebuggerActive() ) { CATCH_TRAP(); } }()
                                                                                    ^
      src/third_party/catch/include/catch.hpp:7813:34: note: expanded from macro 'CATCH_TRAP'
          #define CATCH_TRAP() __asm__("int $3\n" : : ) /* NOLINT */
                                       ^
      <inline asm>:1:6: note: instantiated into assembly here
              int $3
                  ^
      

      catch.hpp contains this code:

       

      #ifdef CATCH_PLATFORM_MAC
      #define CATCH_TRAP() __asm__("int $3\n" : : ) /* NOLINT */
      

       

      Note the absence of any conditional for different assembly code for different architectures or fallback non-assembly code for unknown architectures—which is present in the subsequent CATCH_PLATFORM_LINUX block. (Why do you need different blocks for macOS and Linux?)
