Actually, I think someone a while ago had come up with a solution. I'm not 
sure how proper it is, you can decide. Here's a copy of the post from Fritz 
Test <Fritz.Test at bam.de> :



Recently I ran into the same trouble (signalled to death by 11) with
Outlook Clients moving mails to a Cyrus folder as Jeremy described in
his mail on the info-cyrus list in August last year (see URL above).

I'm using Simon Matter's last SRPM Packages on COMPAQ DS20, RedHat Linux
7.2/Alpha.

With help of the analysis of Jeremy (Thanks) I patched the function
mkgmtime, such that it works for me now. The problem is, that gmtime(&t)
returns a null pointer for my 64-bit system if t is out of some range. I
don't know exactly what range, but I assume that the generated value for
the year must fit in 32 bits?.

Here's a snipped of my code in mkgmtime.c

-----------------------------------------------

  /*
  ** If time_t is signed, then 0 is the median value,
  ** if time_t is unsigned, then 1 << bits is median.
  */
  t = (t < 0) ? 0 : ((time_t) 1 << bits)
     ;

  /* Patch begin */
  /* 
  ** On my 32-bit Debian GNU/Linux 3.0 AMD K6 PC, the algorithm
  ** converges in a range 
  ** from
  **              1901-12-13 20:46:00 GMT -> -2147483640
  ** to 
  **              2038-01-19 03:14:07 GMT ->  2147483647 
  */

  /* 
  ** It segfaults on RedHat 7.2/Alpha if bits > 56, since gmtime (&t) 
  ** returns null pointer.
  ** Hence, set bits to a resonable value <= 56.
  **
  ** Setting, e.g. bits=40, the algorithm converges in a range 
  ** from
  **            -32873-11-12 23:24:00 GMT -> -1099511627760
  ** to 
  **             36812-02-20 00:36:59 GMT ->  1099511627819
  */
  if (bits > 40) {
    bits = 40;
  }
  /* patch end */

  for ( ; ; ) {

    prt (t);
    fprintf (stderr, " ");

Hope this helps
