c/o glibc, which the vast majority of us are using, i suspect:

void
stacktrace (std::ostream& out)
{
	void *array[200];
	size_t size;
	char **strings;
	size_t i;
     
	size = backtrace (array, 200);
	strings = backtrace_symbols (array, size);
     
	if (strings) {

		for (i = 0; i < size; i++) {
			out << strings[i] << std::endl;
		}
		
		free (strings);
	}
}
