I think this is a correct D2 program:


import std.stdio: File;
void main() {
    auto f = File("test.txt", "w");
    f.writef("%c", 'x');
}


But DMD dmd 2.048 gives at runtime:
std.format.FormatError: std.format integral

According to the std.format documentation, "%c" is not a valid format specifier.  The error message could be improved, though.

The program runs fine on 2.059, and the text file is created with 'x' inside.

"%c" format specifier has been supported from 2.058: http://dlang.org/phobos/std_format

It was fixed by the pull request: https://github.com/D-Programming-Language/phobos/pull/298
