Proposed solution

@Tieqiong Tieqiong, could you please look into this issue? We are so close.

Also, please check, there seems to be an error resolving a date in the output header (copyright statement)

This problem is not obvious to solve. It's not very easy to make memory error on python when the logic is correct (it worked for other python versions) and I thought the problem could be on the c++ part, as all the errors are related to read_struct in stru.cc. However I trace back all the memory allocation related to read_struct and I think they are all treated properly, and it must be as every other version/platform works. (There is a test tool for the c modules, but unfortunately it uses cppunit-config which was removed almost 10 years ago...)

Need to test on a local windows machine and see if the problem is actually the memory. The only thing I found related to python3.13, window, and memory is this

Also, please check, there seems to be an error resolving a date in the output header (copyright statement)

interestingly for my local pytest the date and version are correct. Need to test on local windows and check

Thanks @Tieqiong . Hopefully we can reproduce it locally.
