【Codon】With repeated processing, memory consumption increases, Killed is displayed, and processing stops.

[icst005]

I was not sure if there was a report applicable to the same case, so I am reporting it just in case.

In the following environment and execution of the code in codon, the memory usage increases and the process becomes Killed and stops.
When executing the code in Python, there is no increase in memory usage and the process completes to the end.
("owari" is displayed.　　「np07b = None」 is not working in codon?)

If you can get the Log by some means and need to provide it, please contact me.
I will try to help.

From Windowshell, execute the following command
「codon run -release test01.py」

    np07b = np.zeros((99999, 1) , dtype = 'int32')
            
    np.random.seed()
    np07b[0: 99999, 0] = np.random.randint(0, 9, 99999)
  
    np07b = None
    
t01 = time.time()
t02 = t01 - t00
print(t02)
print("owari")

Thanks for issue @icst005 -- we'll look into it. Creating Python objects in Codon allocates memory tracked by the GC, but the GC should be collecting the temporary objects so memory growth definitely shouldn't be unbounded.

Thank you for your comment.

If there is anything else I need to provide, such as additional information, please do not hesitate to let me know.

Seems like a duplicate of #472—same issue with GC and CPython allocation.
