Strings returned by getenv() should not be modified.  FreeTDS should
strdup() first and modify the copy, then free() it later on.

This may be the culprit, in src/tds/locale.c

  s = getenv("LANG");
  if (s && strlen(s)) {
          rewind(in);
          for (i = 0; i < strlen(s); i++)
                  s[i] = tolower(s[i]);
          tds_read_conf_section(in, s, tds_parse_locale, locale);
  }

Perhaps your OS returns a pointer to the true environment string, not a
copy?
