Description
At runtime with some dev commit (I don't know which) I get:
tester.moc:83:28: runtime error: member access within address 0x0000023a6ed0 which does not point to an object of type 'QObjectData' 0x0000023a6ed0: note: object is of type 'QObjectPrivate' 00 00 00 00 98 26 8b af 42 7f 00 00 70 98 6a 29 fc 7f 00 00 00 00 00 00 00 00 00 00 40 98 73 af ^~~~~~~~~~~~~~~~~~~~~~~ vptr for 'QObjectPrivate'
This does not happen with Qt 5.5. I didn't check intermediate versions.
