Hi, net reader,

I found a bug in Turbo C, please reconfirm if it is truely a bug.
======= cut here =======
#include <stdio.h>
#include <alloc.h>

main() {
float far *temp, fix;
int i;

temp = farmalloc(40);
for(i = 0; i< 5; i++)
scanf("%f", temp+i);
}
===== end here ======

The above code does not work but with an error message :
"floating point formats not linked"

But, if we put another statement at the end of the program :

scanf("%f", &fix);

Now, re-compiler and link the code.  It works ok.
It is very obvious that the code "scanf("%f", &fix);" should not
affect the about program like this.  I believe there is a bug
between farmalloc(farcalloc) and scanf("%f",...).

That is what I found.
