<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">In the Python2 interpreter plugin we constuct a QVariant from a typeId
and a pointer to the data. When a method returns e.g. a QVariantMap
in a QVariant, the typeId is QVariant::Map, but toVoidStar() used to
point to the memory where the wrapper QVariant was stored, but the QMap
is actually stored elsewhere, because QTypeInfo<QVariantMap>::isStatic
is true.
It wasn't crashing with Qt4 because in Qt4 QVariantMap was stored in the
QVariant's internal store (the C++ union).
We add template specialization MetaTypeVariant<QVariant> to handle
QVariants differently: now we directly return QVariant::data().</pre>
