Concur with Martin. Most likely it is an OS bug, the same as issue5614.

I get a MemoryError on Windows 10:

>>> float(array.array("L",b"a"*0xFFF+10**80))
Traceback (most recent call last):
  File "", line 1, in 
MemoryError
>>>

[issue27547] Crash or freeze trying to execute b'a' * 0xFFFFFFFFFFFFFFF

[Terry J. Reedy]

Terry J. Reedy added the comment:

Crash reports should include the minimum code needed to produce the crash.  
Adding function calls that never happen because the arguments cannot be 
computed adds noise that obscures the problem.  Here, b"a"*0xFFF 
would require more memory that any current computer has.  Float and array are 
irrelevant.  On Windows, it freezes python.  A MemoryError would be nicer, but 
this may be "won't fix".
