it's possible to remove the linker errors by adding std/exception.d to the to-compile file list but then the program immediatly runs out of memory, even though it doesn't when you don't optimize it.

commenting out the line with errnoEnforce in std/stdio.d fixes my problems (but probably breaks a few things). It's not worthy of a patch but it's good enough for me.

I get the same issue on linux with dmd git head.

The -inline flag causes the issue for me.  I can add -O -release and -noboundscheck without getting the linker issue.

I got that bug, too.

I have a small family of examples here.

-----example1.d:OK-----
import std.stdio;
void main () {
    ubyte [256] buf;
    stdin.rawRead (buf);
}
-----

-----example2.d:Fails with -inline-----
import std.stdio;
void main () {
    ushort [256] buf; // same with uint
    stdin.rawRead (buf);
}
-----

Checked with DMD 2.064.2, DMD 2.065.0 and DMD 2.066-0-b6, the results are roughly the same.

Example 1 is OK.

In example 2, certain optimizations lead to linker errors.  To compile successfully, just run "dmd <file>.d". For versions 2.064 and 2.066, just adding "-inline" causes a linker error. For 2.065, the error requires the full "-release -inline -noboundscheck" to be reproduced locally.

Any news on this one? I think I'm seeing something similar in my code, but it's too much code to pin-point an excerpt and post here.
