/*
|
|
* 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.
