Bug #: 30839
           Summary: BSTR cache corrupts most of cached BSTR entries
           Product: Wine
           Version: 1.5.5
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Keywords: testcase
          Severity: normal
          Priority: P2
         Component: oleaut32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

imitates what pretty large and complex application does, and shows
that BSTR cache in Wine corrupts most of cached BSTR entries:

vartype.c:6145: good_length_entries 225, good_string_entries 162
vartype.c:6148: Test failed: good_string_entries 162 out of 256
vartype.c:6164: good_length_entries 97, good_string_entries 67
vartype.c:6166: Test failed: good_length_entries 97 out of 256
vartype.c:6168: Test failed: good_string_entries 67 out of 256

Under Windows most of cached strings stay valid for pretty long time
after SysFreeString() is called.

Jacek, I'm adding you to the cc: list because you are the authour of BSTR
cache in Wine.
