glibc: printf bug

[Bruce Korb]

Hi all,

I thought that the printf bugs were largely gone in glibc-2.
This has to do with printf argument indexing.  The following
program fails on SuSE 8.2 and works on most any modern UNIX.
It also works if you have the snprintfv library and define
USE_SNPRINTFV :-)

=====================

#include <stdio.h>

#ifdef USE_SNPRINTFV
#include "config.h"
#include <snprintfv/printf.h>
#endif

static const char zSamp[] =
"ch1: 49 ('1') -- ch2: 32 (' ')\n";
static const char zFmt[] =
"ch1: %1$d ('%1$c') -- ch2: %2$d ('%2$c')\n";

static char zBuff[ 128 ];

int
main( int argc, char** argv )
{
    sprintf( zBuff, zFmt, 0x31, 32 );
    fputs( zBuff, stdout );
    return strcmp( zBuff, zSamp ) != 0;
}
