We were having trouble with sendmail core dumping when dealing with
long recipient lists (at least with 5.61 on our Mips machine). I
managed to localize the problem into deliver.c and the deliver()
procedure where the string array "tobuf" was causing the problem -- to
much data was being written into the array and this was corrupting
other structures on the stack.

The following patch fixed that problem.

  			break;
  
  		if (tTd(10, 1))

! 		if (sizeof tobuf - (strlen(to->q_paddr) + strlen(tobuf) + 2) < 0)
  			break;
