this test program:

module testexport;

export void foo1() {}
export void foo2() {}
export void foo3() {}

void main() {}

compiles, but exports in the resulting executable (not a DLL here for
simplicity) are wrong.

>dumpbin /exports testexport.exe
[...]
    ordinal hint RVA      name

          1    0 00003014 D10testexport4foo2FZv
          2    1 00003018 D10testexport4foo3FZv
          3    2 00003010 _D10testexport4foo1FZv
[...]

The object file seems ok, here's a snippet from obj2asms' output:

    extrn    _D10testexport4foo1FZv
    ;expdef expflag=x00, export '_D10testexport4foo1FZv', internal '',
ordinal=x0
    extrn    _D10testexport4foo2FZv
    ;expdef expflag=x00, export '_D10testexport4foo2FZv', internal '',
ordinal=x0
    extrn    _D10testexport4foo3FZv
    ;expdef expflag=x00, export '_D10testexport4foo3FZv', internal '',
ordinal=x0
[...]
    public    _D10testexport12__ModuleInfoZ
