[issue29434] tuple.__repr__ may segv when it contains NULL

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

This looks similar to issue26811.

I think that if the reproducer is found it would be better to fix the case of 
leaking a tuple containing NULL rather than making repr() be aware of NULLs. 
repr() is not the only way to crash with such tuples.

The patch missed `continue;`.
And I couldn't reproduce the problem for now.

I'll reopen when I can reproduce the problem.

New submission from INADA Naoki:

sys.getobjects() contains tuples including NULLs.
Even without pydebug, tuple under construction can be exposed accidentally.

Allowing repr() for such tuples ease investigating what is the tuple.
