Further, when the format string is a literal like the one used
in the
program, the compiler can in theory determine at compile time
that the
format string does not match the rest of the arguments:
readf (" %s, ");
// "No argument for %s"
This is a desired feature but dmd does not have this yet.
Since dmd
provides the front end to gdc and ldc, they don't have this
feature either.
I will log a feature request with Walter.

Compiler bugs are a reality but not *that* common ;-) Thanks for the assistance. I assumed that the compiler would at least throw a line number, to hint at where the problem was.

short programme from "Programming in D" by Ali Cehreli.
Hi, Can anyone assist me with the short D programme. It is taken
straight from "Programming in D" by Ali Cehreli. The code below
is the solution, on page 684.
The Exercise is on Page 27, item 2 half way down the page.
The problem is that the program crashes, when it runs. The only
thing I have changed is the placement of the curly brackets on
new lines, otherwise the code is the same. My text editor is
Sublime 3 - Build 3114.

Here is all the source:
import std.stdio;
void main ()
{
writeln ("Roll the dice .");
int die ;
readf (" %s, ");
if ((die == 1) || (die == 2) || (die == 3))
{
writeln("You won");
}
else if ((die == 4) || (die == 5) || (die == 6))
{
writeln("I won");
}
else
{
writeln("ERROR: ", die , "is invalid");
}
}
Note, this source below, take from the code samples .zip file
works correctly !!
module if_solution_3;
import std.stdio;
void main() {
write("What is the value of the die? ");
int die;
readf(" %s", );
if ((die == 1) || (die == 2) || (die == 3)) {
writeln("You won");
} else if ((die == 4) || (die == 5) || (die == 6)) {
writeln("I won");
} else {
writeln("ERROR: ", die, " is invalid");
}
}

I'm a bit wondering why it happens on floating point stuff... valgrind doesn't have full support for x87 code, which dmd emits all over the place. There is company is Germany, which does Valgrind consultancy, http://www.open-works.net/contact.html which could fix this issue, if you are prepared to throw some money their way. Nick
