Testcase for IStorage_CreateStorage

[Markus Stockhausen]

Hi,

as I'm still working on a resolution to bug #9575 I have digged into
several directions. My current opinion is that IStorage_CreateStorage
for some unkown reason increments the reference pointer of the
associated IStorage object. In native Windows this is not the case.

My 37th try in writing a Wine testcase resulted in the following code
that hopefully shows the difference between the two environments. I put
it somewhere in the storage32 tests to get it running. No warranty for
side effects.

static const WCHAR yyy[] = { 'x','.','t','x','t',0 };
  r = StgOpenStorage( yyy, NULL, 
                      STGM_TRANSACTED | STGM_SHARE_EXCLUSIVE |
                      STGM_READWRITE , NULL, 0, &stg);
  ok(r==S_OK, "StgCreateStorage failed\n");
  if(stg)
  {
    static const WCHAR xxx[] =  
      { 'D','a','t','a','S','p','a','c','e','I','n','f','o',0 };
    IStorage_CreateStorage(stg,xxx,STGM_READWRITE |
                           STGM_SHARE_EXCLUSIVE,0,0,&stg2);
    if (stg2) {
      r = IStorage_AddRef(stg);
      ok(r == 2, "WINE ERROR: refcount should be 2\n");
      IStorage_Release(stg2);
      while ( r ) r=IStorage_Release(stg);
    } else {
      ok( 1 == 2, "IStorage::CreateStorage failed\n");
      IStorage_Release(stg);
    }   
  }

If I got everything in the right place this test should fail on Wine
wheres it will be ok in Windows. Before doing further research I hope
someone of the experts can check if the test really reveals the source
of the above mentioned bug.

Thanks in advance.
