Here is my test code.

import std.stdio;

struct PackageHandler
{
    private auto buffer = appender!(ubyte[])();  // The bug is here
    // private Appender!(ubyte[]) buffer;  // It's ok.

    void test()
    {
        assert(buffer.data.length == 0);  // for test
    }

    void append(ubyte[] data)
    {
        buffer ~= data;
    }

    void reset()
    {
        buffer.clear();
    }
}

class AppenderTester
{
    private PackageHandler handler;

    this()
    {
        handler.test();
    }

    void append()
    {
        handler.append([11, 12, 13]);
    }

    void clear()
    {
        handler.reset();
    }
}

void main()
{
    AppenderTester tester01 = new AppenderTester();
    tester01.append();
    // tester01.clear();

    AppenderTester tester02 = new AppenderTester();
}
