One problem I see immediately that doesn't really affect correctness is that the argument is passed by value, so if you printed a large static char array, it would copy all the data in order to print it.
But I think the real problem is this. From DMC++ docs: If the field_width is the character *, the actual field_width value is taken from the next int arg. If the field_width is negative, it is treated as if the - flag were given and the absolute value of the field_width is used. **** If there are more characters than allowed for by the field_width, then the width is expanded appropriately. **** I think this means, the width passed is not the number of characters you want to print, but the *minimum* number of characters you want to print (with padding). -Steve ----- Original Message ---- > From: Andrei Alexandrescu <[email protected]> > To: Discuss the dmd beta releases for D <[email protected]> > Cc: Richard Webb <[email protected]> > Sent: Thu, June 10, 2010 2:08:00 PM > Subject: Re: [dmd-beta] dmd 1.062 and 2.047 beta > > I can't reproduce the bug, code works for me with 2.047 on Linux.
