| 1 | Pure virtual method ExpectationBase::GetHandle ( ) has been added to this class. | 1) Applications will not provide the implementation for this pure virtual method and therefore cause a crash in the library trying to call this method.
2) The layout of virtual table has been changed. Call of any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications. |

ExpectationBase::AllPrerequisitesAreSatisfied ( ) constCall of this virtual method may result in crash or incorrect behavior of applications because the layout of virtual table has been changed.
ExpectationBase::DescribeCallCountTo ( std::ostream* os ) constCall of this virtual method may result in crash or incorrect behavior of applications because the layout of virtual table has been changed.
ExpectationBase::ExpectationBase [in-charge] ( char const* file, int line )Call of this virtual method may result in crash or incorrect behavior of applications because the layout of virtual table has been changed.
ExpectationBase::RetireAllPreRequisites ( )Call of this virtual method may result in crash or incorrect behavior of applications because the layout of virtual table has been changed.
ExpectationBase::SpecifyCardinality ( testing::Cardinality const& cardinality )Call of this virtual method may result in crash or incorrect behavior of applications because the layout of virtual table has been changed.
ExpectationBase::~ExpectationBase [in-charge] ( )Call of this virtual method may result in crash or incorrect behavior of applications because the layout of virtual table has been changed.
