The following reduced code example fails to link. It seems to be due to DMD checkin 12bb9afb753ad2f2aef65550b960357c63854cbc -- fix Issue 10441 - Static libraries too big. Compiles fine if I try with one version before that. On my Linux x64 box I get: $ rdmd test.d /tmp/.rdmd-1000/rdmd-test.d-C130B18713BE4647AF6BF8F764A06FDD/objs/test.o: In function `_D3std9container32__T10BinaryHeapTAS4test3Bar3FooZ10BinaryHeap3popMFAS4test3Bar3FooZv': __entrypoint.d:(.text._D3std9container32__T10BinaryHeapTAS4test3Bar3FooZ10BinaryHeap3popMFAS4test3Bar3FooZv+0x5c): undefined reference to `_D3std5array25__T5emptyTS4test3Bar3FooZ5emptyFNaNbNdNfxAS4test3Bar3FooZb' // test.d Reduced code example: class Bar { import std.container: BinaryHeap; BinaryHeap!(Foo[]) Heap; struct Foo { int opCmp(Foo ) { return 1; } } } void main() {}

Kenji, it's not a full solution. I've make test case from my project. It's too strange test case, but as it is. A.d: import C; import D; void foo() { Vector2 rsm; readWriteVariable(rsm); } void main() { } B.d: import D; import std.algorithm; void bar() { Vector2[] tc; sort(tc); } C.d: import std.traits; void readWriteVariable(T)(ref T data) { foreach(it; __traits(allMembers, T)) enum vValid = mixin(`is(FunctionTypeOf!(T.` ~ it ~ `) == function)`); } D.d: struct Matrix(T, uint _M) { int opCmp()(auto ref in Matrix b) const { return 0; } pure auto opDispatch(string s)() { enum L = s.length; Matrix!(T, L) ret; return ret; } pure Matrix normalized() { return Matrix(); } } alias Matrix!(float, 2) Vector2; Problem exists only if files compiled into single objs and then linked together. dmd A -c dmd b -c dmd c -c dmd d -c dmd a.obj b.obj c.obj d.obj Error 42: Symbol Undefined _D1D16__T6MatrixTfVi2Z6Matrix8__xopCmpFKxS1D16__T6Ma trixTfVi2Z6MatrixKxS1D16__T6MatrixTfVi2Z6MatrixZi b.obj(b) Error 42: Symbol Undefined _D1D16__T6MatrixTfVk8Z6Matrix8__xopCmpFKxS1D16__T6Ma trixTfVk8Z6MatrixKxS1D16__T6MatrixTfVk8Z6MatrixZi b.obj(b) Error 42: Symbol Undefined _D1D16__T6MatrixTfVk6Z6Matrix8__xopCmpFKxS1D16__T6Ma trixTfVk6Z6MatrixKxS1D16__T6MatrixTfVk6Z6MatrixZi b.obj(b) Error 42: Symbol Undefined _D1D16__T6MatrixTfVk9Z6Matrix8__xopCmpFKxS1D16__T6Ma trixTfVk9Z6MatrixKxS1D16__T6MatrixTfVk9Z6MatrixZi If something is removed from test case, then linking is ok.

And updated the PR to fix it.
