[PyQt] pyqtWrapperType not usable as metaclass in 4.12?

[Georg Brandl]

Hi all,

after updating PyQt4/sip to 4.12/4.19, this snippet produces a segfault
(I've reproduced this with two builds, one built for Ubuntu, one on Mac):


import PyQt4.QtCore

class D(object):
    __metaclass__ = PyQt4.QtCore.pyqtWrapperType


Is pyqtWrapperType not supposed to be instantiable anymore?

The fault occurs in pyqtWrapperType_init.  A diff between 4.11.4 and 4.12
shows this change in the function:

-    pyqt4ClassTypeDef *pyqt_td = (pyqt4ClassTypeDef *)((sipWrapperType
*)self)->type;
+    const pyqt4ClassPluginDef *pyqt_td = reinterpret_cast<const
pyqt4ClassPluginDef *>(sipTypePluginData(((sipWrapperType *)self)->wt_td));

Thanks,
Georg
