[issue42034] Unchecked return in Objects/typeobject.c and possible uninitialized variables in cls and new_mro

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

There is no bug in this code. The list "temp" contains only 2- and 3-tuples. 
PyArg_UnpackTuple() never fails.

[issue42034] Unchecked return in Objects/typeobject.c and possible uninitialized variables in cls and new_mro

[Sagar Pant]

New submission from Sagar Pant :

The return value of a function that is potentially used to initialize a local 
variable is not checked. Therefore, reading the local variable may result in 
undefined behavior.

Our AI analyzer found that this function is called for a total of 43 times. Out 
of these 43 times, the return value from the function call is checked at 42 
instances. This is the only instance where the code misses to check the return 
value for success or failure.

Once such correct reference usage found in Python/hamt.c at line 2805 .
