Will revisit that code, it was designed to verify available size and expand
before copying - evidently there is, or was, a problem somewhere.

It would help (or at least it might) if I knew which build of the dll was
involved.

I find it rather shocking that it seems to bypass multiple levels of
try..except inside the dll and the component to knock out the application
itself!

Dear Russell,



I encounter some zipping problem on Windows 10. It occurs during
execution of the add command.

Following error is shown: wcsncpy-s followed by Abnormal program
termination

The application crashes completely, TRY - EXCEPT has no effect



I use latest versions of the zip libraries: 1.9.2.0016 and dll's:
1.9.2.127

The problem occurs only on one specific 64-bits applications on Windows
10.
Other applications using exactly the same libraries and functions do
not show this problem.

The same application as 32 bits on Windows 10 also shows no problem
(zipping exactly the same directory), while the 64 bits application on
Windows 7 also shows no problem



Kind Regards,



Paul Nauta
