cat > bar.d << CODE
struct Bar
{
    bool opCmp(ubyte val) { return false; }
}
CODE

cat > foo.d << CODE
import bar;

struct Appender
{
    Bar[] tokens; // references TypeInfo of Bar!(ubyte)
    // TypeInfo references __xopCmp
}

void main()
{
}
CODE

dmd -lib bar
dmd foo bar.a

----
foo.o:(.data._D18TypeInfo_S3bar3Bar6__initZ+0x40): undefined reference to
`_D3bar3Bar8__xopCmpFKxS3bar3BarKxS3bar3BarZi'
----

It seems, that during compilation of the bar lib the generated _xOpCmp function
isn't emitted to the object file.
