By the time QObject::destroyed() is emitted from ~QObject(), sender no
longer is-a SenderObject, only a QObject, so calling a SenderObject
member function on it is UB.
Says UBSan:
tst_qfuture.cpp:3854:84: runtime error: member call on address 0x60200000e550 which does not point to an object of type 'SenderObject'
0x60200000e550: note: object is of type 'QObject'
00 00 00 00 e8 3f 96 c9 51 7f 00 00 80 3e 00 00 c0 60 00 00 02 11 00 00 08 00 00 00 16 00 00 72
^~~~~~~~~~~~~~~~~~~~~~~
vptr for 'QObject'
Fix by removing the QObject::connect().
This, of course, breaks the test's WHEN, but I don't see how to keep
that WHEN without the UB. At least the THEN part is not invalidated,
and there doesn't appear to be another test that tests that destroying
objects before signal emission results in a cancelled future.
