Are we relying on std::string data formatters working here? Seems like a dangerous change as we would require any new ports of LLDB to have std::string formatters working or this test will fail?

That did not occur to me. Would shoving the data into a char * be acceptable?

I would just make a large buffer and use snprintf:

char buffer[4096];
char *p = buffer;
char *end = p + sizeof(buffer);
p += snprintf(p, end - p, "a_as_A->a() = '%s'\n", a_as_A->a());
p += snprintf(p, end - p, "a_as_A->b() = '%s'\n", a_as_A->b());

New version, which does not rely on pretty-printers.
