DMD version 2.063.0 through .2. Worked ok in 2.062. 32/64 bit Linux.

This needs two files, test.d and bug.d
///////////
module test;

import bug;

void main()
{

}

///////////
module bug;

struct A()
{
    int opCmp(const ref A p) const
    {
        return 0;
    }

    string toString()
    {
        return "";
    }
}

struct B()
{
    void foo()
    {
        auto a = new A!();
    }
}

struct C
{
    alias A!() a_t;

    this(B!() b)
    {

    }
}

When compiled this way there are no errors:

dmd test.d bug.d

However, when compiled this way I get link errors:

dmd -c bug.d && dmd test.d bug.o

test2.o:(.data._D23TypeInfo_S3bug6__T1AZ1A6__initZ+0x40): undefined reference to `_D3bug6__T1AZ1A5opCmpMxFKxS3bug6__T1AZ1AZi' test2.o:(.data._D23TypeInfo_S3bug6__T1AZ1A6__initZ+0x48): undefined reference to `_D3bug6__T1AZ1A8toStringMFZAya'

Tried on Windows but it works there, it's maybe a posix-only issue.

Reproduced this problem on my Linux amd64 box with dmd git HEAD.

git bisect indicates that the offending commit was 67fbf5753e9d4a276c354e952ed2f888efcb714c, which was apparently a fix for issue 7511.

The link-failure could see also on Windows 64bit codegen (use -m64).

dmd -m64 -c bug.d && dmd -m64 test.d bug.obj
