New submission from jvoisin <jvoi...@google.com>:
The attached file produces the following stacktrace when opened via
`zipfile.ZipFile`, on Python 3.7.5rc1:
```
$ cat ziprepro.py
import zipfile
import sys
zipfile.ZipFile(sys.argv[1])
```
```
$ python3 ziprepro.py
crash-4da08e9ababa495ac51ecad588fd61081a66b5bb6e7a0e791f44907fa274ec62
Traceback (most recent call last):
File "ziprepro.py", line 4, in <module>
zipfile.ZipFile(sys.argv[1])
File "/usr/lib/python3.7/zipfile.py", line 1225, in __init__
self._RealGetContents()
File "/usr/lib/python3.7/zipfile.py", line 1310, in _RealGetContents
fp.seek(self.start_dir, 0)
ValueError: cannot fit 'int' into an offset-sized integer
```
The ValueError exception isn't documented as a possible exception when using
zipfile.ZipFile ( https://docs.python.org/3/library/tarfile.html ).
