Description of problem:

Hello there,

I just tried to compile package nss_db-2.2-20 from Redhat 9.0
with compiler flag -Wall.

The compiler said

../db_load/db_load.c:810: warning: operation on `instr' may be undefined


The source code is

                        c = digitize(dbenv, *instr, &e1) << 4 |
                            digitize(dbenv, *++instr, &e2);

This is well broken. You would be better off with

                        c = digitize(dbenv, *instr, &e1) << 4 |
                            digitize(dbenv, instr[ 1], &e2);
                        ++instr;


Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. compile with -Wall
2.
