Differences beetwen release and debug version

[Lucian]

Hi,

I have the following issue:

For debug version I have no problem executing the code, but for release version the code fails, with invalid type.

If I used the following line,

     m_currentstruct[m_currentfield] = m_currentdata.str();            

where the types are:
  std::wstring m_currentdata;
  std:string m_currentfield;

  XmlRpcValue m_currentstruct;

the returned type for m_currentstruct[m_currentfield] is:
in debug: 4
in release:  -1414856704

Could be a problem with project settings? How could I   forced the type to be TypeString?

Thanks,
Lucian
