I built clang/LLVM in ubuntu20.04 by downloading the llvm-project of github. According to the construction process of the official website, I executed the last step. When I executed the make command, an error was reported：
... [ 95%] Building C object tools/llvm-c-test/CMakeFiles/llvm-c-test.dir/metadata.c.o [ 95%] Building C object tools/llvm-c-test/CMakeFiles/llvm-c-test.dir/object.c.o [ 95%] Building C object tools/llvm-c-test/CMakeFiles/llvm-c-test.dir/targets.c.o [ 95%] Linking CXX executable ../../bin/llvm-c-test collect2: fatal error: ld terminated with signal 11 [Segmentation fault], core dumped compilation terminated. make: *** [tools/dsymutil/CMakeFiles/dsymutil.dir/build.make:335: bin/dsymutil] Error 1 make: *** Deleting file 'bin/dsymutil' make: *** [CMakeFiles/Makefile2:91054: tools/dsymutil/CMakeFiles/dsymutil.dir/all] Error 2 make: *** Waiting for unfinished jobs.... [ 95%] Built target llvm-c-test [ 95%] Built target llc [ 95%] Built target bugpoint make: *** [Makefile:152: all] Error 2
how to solve this problem?
