SG, submitted in r219534. Feel free to replace this line with smth. like

#if defined(__linux__)
  // info->dlpi_name on Linux contains empty string for main executable.
  const char *name = data->first ? data->main_exec_name : info->dlpi_name;
  const char *name = info->dlpi_name;

if you find it working better / more reliable on FreeBSD systems. I'd also
really appreciate if you could test this change by introducing a crash in
and verifying that symbolization works as expected. Thanks!
