What steps will reproduce the problem?
Unable to reproduce consistently.

What is the expected output? What do you see instead?

the end:

Note that the error only seem to occur for zip files that are at least a few 
megabytes large.

Please provide some details on the problem:
- Was the encrypted zipfile created with this library?
- Was the decryption performed with this library?

Our best chance to solve the problem is a sample file.

Yes to both questions. I don't have a sample file I can attach.

I've added a testcase with a jpg file of more than 5MB. "Unfortunately", I 
don't encounter an error. Can you compare your code with the testcase? Do you 
encrypt text or binary data?

Text and binary mix; the code is comparable. Does the library do CRC32 handling 
properly? The files could somehow have become corrupted (either by winzipaes, 
or due to problems during file copy, etc), in which case the crc check 
should've kicked in.

As there's no example file available and I was not able to reproduce the 
problem, I take the liberty to "invalidate" this issue.
