+/*
+ * This file exists because tst_qsharedpointer.cpp is compiled with
+ * QT_SHAREDPOINTER_TRACK_POINTERS. That changes some behavior.
+ *
+ * Note that most of these tests may yield false-positives in debug mode, but
+ * they should not yield false negatives. That is, they may report PASS when
+ * they are failing, but they should not produce FAILs.
+ *
+ * The reason for that is because of C++'s One Definition Rule: the macro
+ * changes some functions and, in debug mode, they will not be inlined. At link
+ * time, the two functions would be merged.
