test case
Compiling test case with -O gives

It's dustmited from project of 14k lines.
If anyone know how to reduce it more bienvenue.

Guuuuys please stop playing with linker's symbols. These regressions are annoying.

I can't reproduce this.
I had to make the following modifications (add two module statements):
diff --git a/perfontain/binary.d b/perfontain/binary.d
index ac4bc19..4a4ac00 100644
--- a/perfontain/binary.d

Не юзайте рдмд. Собирать отдельно.
Новый тесткейс + скрипт для сборки.
Спасибо!

Is this really a regression? The second archive fails to link with DMD 2.065.0 and fails to compile with 2.064.2. In which version did this work?
Comment #6 by temtaime — 2014-05-06T16:36:54Z
Too strange it compiles ok with 065 but yes i cannot link it with 065 right now so change the state.
Comment #7 by ketmar — 2014-08-20T02:46:40Z
i just checked this with DMD 2.066 on win32, and everything works ok. it also works with current HEAD on 32-bit GNU/Linux. maybe we should close this bug?

Finally reduced test case:
C.d:
------------
import E;
void foo() { Vector4 v; read(v); }
void main() {}
D.d
------------
import E;
void bar() { Vector4 v; read(v); }
E.d
------------
struct Matrix(T, uint M, uint N = M)
{
string toString() const { return ""; }
int opCmp()(auto ref in Matrix v) const { return 0; }
T[][] arr;
auto transposed()
{
Matrix!(T, N, M) r1;
Matrix!(T, M, 1) r2;
}
}
alias Matrix4 = Matrix!(float, 4);
alias Vector4 = Matrix!(float, 1, 4);
void read(T)(T data)
{
foreach (it; __traits(allMembers, T))
{
static if (mixin(`__traits(compiles, &data.` ~ it ~ `)`)) {}
}
}
build.bat
------------
dmd -c C.d
dmd -c D.d
dmd -c E.d
dmd C.obj D.obj E.obj

It was a duplication of issue 7469.
When the Matrix template has instantiated, its integer value parameters had caused wrong mangled names for templates in separate compilation, and it had caused link failure. If the two uint template value parameters are changed to int, the link failure had disappeared.
Since 2.066, issue 7469 is properly fixed, so the problem does not happen anymore in git HEAD.
