Receiving fatal error assigning QSharedPointer in QtTest - c++

Question

In TestGroup_Person, when I retrieve a QSharedPointer<-JB_TableRowProt> from JB_PersonDao and assign it to QSharedPointer<-JB_TableRowProt> aGroup_Person (in .h), I then get this error in the methods of TestGroup_Person.
Alternatively, if I retrieve a QSharedPointer<-JB_TableRowProt> from JB_DaoProt in each method (and don't assign it to QSharedPointer<-JB_TableRowProt> aGroup_Person), it works fine.
Can someone explain to me why this assignment appears to be causing the error please?
I got this error:
QFATAL : TestGroup_Person::test_getDBTable_Name() Received signal 11
Function time: 0ms Total time: 0ms
FAIL! : TestGroup_Person::test_getDBTable_Name() Received a fatal error.
Here's the code:
main:
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QStringList arguments = QCoreApplication::arguments();
QFile aFile(DATABASE_FILENAME); // remove existing SP3.db
if (aFile.exists())
aFile.remove();
map<QString, unique_ptr<QObject>> tests;
tests.emplace("group_person", make_unique<TestGroup_Person>());
if (arguments.size() >= 3 && arguments[1] == "-select") {
QString testName = arguments[2];
auto iter = tests.begin();
while(iter != tests.end()) {
if (iter->first != testName) {
iter = tests.erase(iter);
} else {
++iter;
}
}
arguments.removeOne("-select");
arguments.removeOne(testName);
}
int status = 0;
for(auto& test : tests) {
status |= QTest::qExec(test.second.get(), arguments);
}
return status;
}

Relevant method of JB_DaoProt:
QSharedPointer<JB_TableRowProt> JB_DaoProt::getJoinTableObject()
{
JB_TableRowProt* aJoinTable = new_JoinTableRowProt();
QSharedPointer<JB_TableRowProt> pJoinTable(aJoinTable);
return pJoinTable;
