[dspam-users] Divide by zero in hash_drv.c (3.6.0-STABLE)

  Hello,
  
  After a while, I got a lot of divide by zero errors with dspam 3.6.0,
using the hash driver. Here's a traceback:

  The bug seems to be here:
  
fpos = sizeof(struct _hash_drv_header) +
    ((hashcode % header->hash_rec_max) * sizeof(struct _hash_drv_spam_record));
    
  For a strange reason header->hash_rec_max is zero.
