memory leak (gif.c) for Magick 6.2.6

[swiss_knife]

(detected with Purify on Windows XP) must be:

static LZWInfo *RelinquishLZWInfo(LZWInfo *lzw_info)
{
lzw_info->stack->codes=(unsigned long *) RelinquishMagickMemory(lzw_info->stack->codes);
lzw_info->stack=(LZWStack *) RelinquishMagickMemory(lzw_info->stack);
lzw_info=(LZWInfo *) RelinquishMagickMemory(lzw_info);
return((LZWInfo *) NULL);
}


instead of:

static LZWInfo *RelinquishLZWInfo(LZWInfo *lzw_info)
{
lzw_info->stack=(LZWStack *) RelinquishMagickMemory(lzw_info->stack);
lzw_info=(LZWInfo *) RelinquishMagickMemory(lzw_info);
return((LZWInfo *) NULL);
}
