In a multithreaded application, if a DLL's DllMain makes a call to _set_se_translator, you may experience a memory leak in the CRT.
This problem occurs if you used the _beginthreadex API to create the thread because the initialization order in the CRT causes the per thread data (PTD) structure for the thread to be allocated two times.
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that this article describes. Apply it only to systems that are experiencing this specific problem.

You can avoid this problem by calling _set_se_translator at the beginning of your thread procedure instead of in DllMain. It is not a good idea to call CRT functions such as _set_se_translator in DllMain.
You can also work around the problem by using CreateThread instead of _beginthreadex to start your threads.
