VLD detects memory leaks in googletest library building project as Multi-threaded Debug #15

Open netmonitoring opened 2 years ago

netmonitoring commented 2 years ago

VLD detects memory leaks in googletest library building project as Multi-threaded Debug (/MTd) (output below).

Building the project as Multi-threaded Debug DLL (/MDd), VLD does not catch whose leaks.
