Commit ID 939b694bfda27017c34a8cdccc81f2bb2ef44079
Author George Sobala

Fix for profile-build failure using gcc on MacOS Fixes https://github.com/official-stockfish/Stockfish/issues/3846 , where the profiling SF binary generated by GCC on MacOS would launch but failed to quit. Tested with gcc-8, gcc9, gcc10, gcc-11. The problem can be fixed by adding -fvisibility=hidden to the compiler flags, see for example the following piece of Apple documentation: https://developer.apple.com/library/archive/documentation/DeveloperTools/Conceptual/CppRuntimeEnv/Articles/SymbolVisibility.html For instance this now works: make -j8 profile-build ARCH=x86-64-avx2 COMP=gcc COMPCXX=g++-11 No functional change
