The actual ELF executable (on Linux at least) using libbactrace are those started by /usr/bin/gcc (which is only a wrapper; that program don't use libbacktrace directly but starts other executable like cc1 and cc1plus). The cc1plus executable is using libbacktrace. The RefPreSys inference engine is also using libbacktrace.
