argusarchive (rasort) segfaulting

So, I'm not sure exactly how this happened... argusarchive and rasort have
been working nicely for quite some time now. I began to notice that all of
my archived files no longer had any data in them and so manually stepped
through argusarchive to discover that it was a problem with rasort.

I'm running this on a Redhat AS3 box dual 3.6Ghz procs and 5Gb of memory.

The argus data file is ~ 600Mb in size.

It seems that ArgusCalloc() isn't too happy but I'm not quite sure why.

Any help would be greatly appreciated.


A clip of the code shows:
void *
ArgusCalloc (int nitems, int size)
   unsigned int *retn = NULL;
   int bytes = nitems * size;

   if (size) {
      retn = (unsigned int *) calloc (1, bytes + 4);

      *retn = 0x45672381;

   ArgusDebug (4, "ArgusCalloc (%d, %d) returning 0x%x\n", nitems, size,
   return ((void *) retn);
