1.
Machine: DEC VAX
Operating system: ULTRIX 3.0

File: load.c
Function: load_average

The variable 'offset' is declared as 'signed' while the
nlist structure is defined in <nlist.h> as:

struct	nlist {
 char *n_name; /* for use when in-core */
 unsigned char n_type; /* type flag, i.e. N_TEXT etc; see below */
 char n_other; /* unused */
 short n_desc;  /* see <stab.h> */
 unsigned long n_value; /* value of this symbol (or sdb offset) */
};

The address of "_avenrun" happens to be 2148358396 and offset takes instead
the values -2146608900 so that the following lseek fails.

Here it is:

(gdb) p nl
$1 = {{n_name = 0xc56 "_avenrun", n_type = 9 '\t', n_other = 0 '\000', n_desc =
(gdb) n
(gdb) p offset
$2 = -2146608900
(gdb)


As a patch I changed the declaration of 'offset' adding an 'unsigned',
initialized it to 0 and tested it against 0; I also added 'unsigned'
in the cast

File: glob.c

calls rindex and not strrchr

File: job.c

calls getdtablesize that doesn't exist
