Hi! For example i have library with structure like ModuleA/test.cpp, ModuleB/test.cpp, then i build it like: #Building library clang++ -c ModuleA/test.cpp -o ModuleA/test.o clang++ -c ModuleB/test.cpp -o ModuleB/test.o libtool -o module.a ModuleA/test.o ModuleB/test.o #Now reproducing build steps from Xcode #Compiling... clang++ -c main.cpp -o main.o #Linking... clang++ -Xlinker -reproducible -o main main.o module.a Now if we launch lldb main, we cant set breakpoint in file ModuleB/test.cpp, only in ModuleA/test.cpp, if link without -Xlinker -reproducible, both breakpoints working as expected. Also dsymutil completely delete symbols for "duplicate" library if link with reproducible flag. It's just example, in real static library i can't change behavior of building process, and can't change names of producing object files. Xcode always set -Xlinker -reproducible flag, and i don't know how to disable it, and my debugging process partially broken. ENV: macos: 15.4.1 Xcode: 16.2
