It's using Symantec Endpoint Protection 11.0.2000.1567 - all the bells and =
whistles.

I blamed AVS at first, but the problem also persists on machines that do no=
t have any AVS installed. I double checked and ran another test today on a =
different machine that also ended the same way (exact same spot too), but o=
nly at 100k iterations.

But, it should be noted that the stackdump has occurred at different points=
, in different threads (as opposed to main). I can try to provide those if =
anyone is interested.=20

Thank you for the sanity check.


I'll test with 1.7 but I just wanted to say that it's not AVS/PFW to blame =
here. Could it possibly be Windows Explorer itself? Again, it does seem to =
occur more often when an explorer window is open to the output directory, i=
n which it refreshes the status of the files being opened/closed every so o=
ften.

It would also be nice to know if someone else can reproduce the issue; perh=
aps just leave it running on a computer overnight.

Regards,
Stefan
