--- Comment #2 from H.J. Lu <hjl.tools at gmail dot com> ---
The reduced test:

bool from_chars_advanced___trans_tmp_3;
char *fastfloat_strncasecmp_input2;
void from_chars_advanced() {
  char running_diff;
  for (int i = 0; i < 5; i++)
    running_diff |= fastfloat_strncasecmp_input2[i];
  from_chars_advanced___trans_tmp_3 = running_diff;
}
