Bug #26878 *printf argument swapping

The *printf family has a bug when pointing to the same argument with different types. Probably the same memoryaddress is used for casting when formatting the argument.

Reproduce code:
printf ( 
   'Int: %1$d and as string: %1$s', 
   'some string' 

// Note that the same happens when 
// using any of the other printf
// functions

Expected result:
Int: 0 and as string: some string

Actual result:
Int: 0 and as string: 0
