The function 'lmd' is called in the signal handler (sigchild).
Here the affected source lines in this function:

void lmd(const char *sourcename, int line, int actlevel, const char *messtr, ...)

  long    t;
  struct    tm *tmptr;
  char    *date;
  WORD    err, j, i = 1;
  va_list    ap;


  if (lmd_lvlrng[actlevel - 1]) {
    tmptr = localtime(&t);
    date  = asctime(tmptr);

    if (!lmdinit) {
    } else {
       /*  get locale setting */
       strcpy(m_current_locale, setlocale(LC_CTYPE, NULL));
       /* set locale to "C" because of %s in format messtr -
          not all languages have UTF8 :-( */

       /* during the setlocale the process is hanging */
       setlocale(LC_CTYPE, "C"); /* <<-- */

       vfprintf(lmd_fp, messtr, ap);
       /* set locale to the old value */
       setlocale(LC_CTYPE, m_current_locale);
       fprintf(lmd_fp, "\n");
       lmd_byteswritten = ftell(lmd_fp);
