It does, because it uses the debug information generated by the compiler. both clang and gcc produce a good quality DWARF (http://www.dwarfstd.org/ http://www.dwarfstd.org/), which contains everything needed to unwind the stack. In Bacward-cpp I do use the unwinder provided by libgcc, which is in fact extracting all the information from DWARF. This is as accurate as GDB can be, it uses the same debug information.
