It seems very strange that a symlink should be causing a segmentation fault when a copy does not. The "ar" program that you are running - is this the binutils ar binary or is it an alias/symlink for the gcc-ar script ? If you have the symlink in place and you run: ar crs --plugin /usr/lib/bfd-plugins/liblto_plugin.so.0.0.0 foo.a foo.o bar.o Does that work ? Does the problem persist if you use the current mainline development sources for the binutils rather than the 2.34 release ?

It also seems like the LLVMgold.so plugin does not have the same problem. This
similar sequence works with this plugin:
echo "int foo(){}" | clang -flto -O2 -c -x c -o foo.o -
echo "int bar(){}" | clang -flto -O2 -c -x c -o bar.o -
ln -s /usr/lib64/LLVMgold.so /usr/lib/bfd-plugins/
ar crs foo.a foo.o bar.o
