New submission from Yuval Greenfield <[email protected]>:
These lines fail on Windows in a surprising way:
# -*- coding: utf8 -*-
import threading
print("threading %s" % threading)
Normally they would throw this:
```File
"C:\Python36\Lib\site-packages\missinglink_kernel\callback\log_monitor.py",
line 1
SyntaxError: encoding problem: utf8```
But attached is a file that throws this instead:
```
Traceback (most recent call last):
File
"C:\Python36\Lib\site-packages\missinglink_kernel\callback\log_monitor.py",
line 2, in <module>
import threading
NameError: name 'threading' is not defined
```
It seems that the amount of lines in the file will cause the exception hiding
bug to manifest.
This issue did reproduce on my Windows machine here:
* Python 3.6.4 (v3.6.4:d48eceb, Dec 19 2017, 06:54:40) [MSC v.1900 64 bit
(AMD64)] on win32

It did NOT reproduce on my Mac at all:
