Code:

# private import std.stdio, std.process;
#
# void main()
# {
#   writefln("Some text");
#   writef("Another text");
#   std.process.system("pause");
# }

Compiled with dmd 0.139 win32, executed it outputs:

Some text
Press any key to continue . . .
Another text

It's a buffered output normal behavior or something wrong with pause call? Do you guys think this is a bug?

I'm pretty sure, even with cout and friends in C++, you have to flush the stream before you want to run a system call like that.

On a tangent, that's horribly inefficient.  I'm sure there is (or should be) a function to wait for input, and if there is not, piping it ain't the way, is it?

Anyway, try adding a fflush in there before the pause, e.g.:

fflush(stdio);

Ok, I suspect this was the case. Though I think I've done this with C (don't know if printf in C behave like this) and C++ and despite of buffers I could never note such an excesive buffering result. I'll keep moving, Thanks.

Yes, yes, that's the one.  I've not done enough console programming of late :$.
