[Bug libc/2072] New: memory leak in stdio-common/printf_fp.c

[heiko dot nardmann at secunet dot com]

In stdio-common/printf_fp.c there are some locations (handling error  
situations) in function _printf_fp() where the deallocation of memory for  
wbuffer is not handled. E.g. the macros PADN() und outchar() return to caller  
without checking wbuffer. I'm not sure whether this is intentionally done or  
not.  
  
#define outchar(ch)							      \  
  do									      \  
    {									      \  
      register const int outc = (ch);					      \  
      if (putc (outc, fp) == EOF)					      \  
	return -1;							      \  
      ++done;								      \  
    } while (0)  
  
#define PADN(ch, len)							      \  
  do									      \  
    {									      \  
      if (PAD (fp, ch, len) != len)					      \  
	return -1;							      \  
      done += len;							      \  
    }									      \  
  while (0)
