[issue29242] Crash on GC when compiling PyPy

[Ned Deily]

Ned Deily  added the comment:

I agree with Zachery that this issue should be closed. There has been no 
activity on it since it was opened three years ago and no indication that it 
has been an ongoing problem. I'm not even sure what the current state of using 
cPython 3 to build PyPy is. If someone can reliably reproduce a crash when 
compiling with a currently support Python 3 version, they can re-open this with 
appropriate supporting documentation.

I suggest not to close this issue, this is an opportunity to investigate 
whether Python3 has this problem as well.

Python 2 is EOL, so I think this issue should be closed.

When compiling the PyPy default branch [1] on a Debian testing machine with
