[issue43616] random.shuffle() crashes with Unhandled exception

[Stefan Behnel]

Stefan Behnel  added the comment:

Almost certainly not a bug in CPython's stdlib.

Possibly something worth investigating in lxml, although, as stated in issue 
43618, random.shuffle() simply does not work on lxml.etree Elements.

Could you post code that fully reproduces the problem?

I suspect the root cause for the bug is in lxml (a third-party library), not in 
CPython itself.

[issue43616] random.shuffle() crashes with Unhandled exception

[Rowan Sylvester-Bradley]

New submission from Rowan Sylvester-Bradley :

When I do 
  random.shuffle(questions_element) 
(questions_element is an element generated by lxml via the code
  questions_element = exams.find("questions") )
I get a crash:
Unhandled exception at 0x7FFD7AE8EF89 (ntdll.dll) in python.exe: 
0xC374: A heap has been corrupted (parameters: 0x7FFD7AEF77F0).

Is there a way to work around this?

Thanks - Rowan
