// This tests intrusive_ptr is working okay. It also checks that there are no memory leaks in the
|
|
// class that intrusive_ptr is pointing via a counting mechanism in the constructors and destructor of Klass.
|
|
// In order to test that there are no leaks of the intrusive_ptr class itself (as it is created on the heap)
|
|
// the runtime tests can be run for a long time to monitor memory leaks using memory monitor tools
|
|
// like 'top'. There is a wrapper for intrusive_ptr in intrusive_ptr_wrapper.h which enables one to
|
|
// count the instances of intrusive_ptr. Uncomment the INTRUSIVE_PTR_WRAPPER macro to turn this on.
|
|
//
|
|
// Also note the debug_shared flag which can be set from the target language.
