Subject: B20.1: byacc bug (Windows NT 4.0 server)

Problem description:

After using the following byacc compilation command, the resulting file
has wrong code inside :

byacc -d file name

Extract of resulting file (see >>>):
===============================================================
...
#define RET_CLI_IVQUAL 5
#define RET_CLI_NOCOMD 6

>>>spec();}
>>>break;
case 66:
#line 266 "s7mp_cli_yacc.y"
{tree_insert_element_noupcase(S7MP_K_TRACE_FILE,yyvsp[0]);}
break;
case 67:
...
===============================================================

Normally, the correct resulting code must be:

===============================================================
...
#define RET_CLI_IVQUAL 5
#define RET_CLI_NOCOMD 6

#line 78 "y.tab.c"
#define T_IDENT 257
#define T_FILE_SPEC 258
#define T_EQUAL_AND_VALUE 259
#define T_EOL 260
...
    yym = yylen[yyn];
    yyval = yyvsp[1-yym];
    switch (yyn)
    {
case 1:
#line 155 "..\base\s7mpmisc\s7mp_cli_yacc.y"
{first_error = 1;lex_init();begin_verb();current_state = STATE_VERB;}
break;
case 3:
#line 163 "..\base\s7mpmisc\s7mp_cli_yacc.y"
{return RET_CLI_NORMAL;}
break;
case 4:
#line 166 "..\base\s7mpmisc\s7mp_cli_yacc.y"
{return RET_CLI_NOCOMD;}
break;
case 5:
#line 169 "..\base\s7mpmisc\s7mp_cli_yacc.y"
{return RET_CLI_NOCOMD;}
break;
...
case 66:
#line 266 "..\base\s7mpmisc\s7mp_cli_yacc.y"
{tree_insert_element_noupcase(S7MP_K_TRACE_FILE,yyvsp[0]);}
break;
case 67:
...

===============================================================
The same source file on Unix system produces a correct resulting file
(y.tab.c)

Thank for your help. We have re-installed the product and the same
problem occurs.
