Thank you.  I've applied the patch, and I initially saw
the 0xC0000374 error, too.

Then I installed some Memory Validator software [1] to
try to learn more (which I have a license for, but had
never installed on my new OS).

However, I am not able to reproduce the 0xC0000374
anymore.  With or without Memory Validator running, nor
from the shell, nor within Visual Studio's debugger.
The 0xC0000374 seems to have suddenly disappeared, but,
I have not changed or recompiled anything, as far as I
know!  :(

Are you still seeing the 0xC0000374 on your end?


Regards,

Bill
