Problems with Data Types, High Severity (1)
task.h
namespace tbb::internal
[+] class scheduler (1)
| Change |
Effect |
| 1 | Pure virtual method scheduler::enqueue ( tbb::task&, void* ) has been added to this class. | 1) Applications will not provide the implementation for this pure virtual method and therefore cause a crash in the library trying to call this method.
2) The layout of v-table has been changed. Call of any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications. |
