[gdal-dev] VS2010-VS2013 s57

[Dmitriy Baryshnikov]

Hi,

I have such error: the GDAL compiled with VS2010-VS2013 in s57 driver 
loose all additional fields values. But the same code compiled with gcc 
or previous VS works fine.
I found the root of problems here (ogr\ogrsf_frmts\s57\s57reader.cpp:932):

    const char *pszAcronym = poRegistrar->GetAttrAcronym(nAttrId);
    iField = poFeature->GetDefnRef()->GetFieldIndex(pszAcronym);

The pszAcronym always empty.

The problem comes from this function (ogr\ogrsf_frmts\s57\s57.h:140):

    const char *GetAttrAcronym( int i )
         { return GetAttrInfo(i) == NULL ? NULL :
    aoAttrInfos[i]->osAcronym; }

It seems to me that during execution this function I have |situation 
when||c_str()|result becomes invalid (the|std::string|is destroyed or a 
non-const member function of the string is called).

If I change function

    const char *GetAttrAcronym( int i )
         { return GetAttrInfo(i) == NULL ? NULL :
    aoAttrInfos[i]->osAcronym.c_str(); }

the problem gone.

So I need some confirmation/verification my ideas.
If I'm right, I can make changes to s57 driver.

Best regards,
     Dmitry
