Although there is no memory leak in the MFC dll project, it is reporting a memory leak.

[sym457]

Although there is no memory leak in the MFC dll project, it is reporting a memory leak.

The symptom occurs when vld.h is added to the vs2019 precompiled header.

If you add vld.h to the top of the class source (cpp) file and cause a memory leak, the memory leak is reported normally, but the location of the memory leak is not displayed.
Please confirm.

Thank you.
