crash with python3.6.2 and readline

What is the procedure for adding to bug report #54728.
<https://trac.macports.org/ticket/54728>
Here is a summary of what happened on my machine:
<https://trac.macports.org/ticket/54728>
1. Installed python3.6.2 without specifying a variant.
2. This version is stable (that is, no crash) but interaction with
readline is faulty.
3. Installed python3.6.2 +readline.
4. Installed py36-readline as suggested by the installation script for
the previous step.
5. the new version of python, in interactive mode, crashes when I type
carriage return, with message like
Python(21762,0x7fffb987c3c0) malloc: *** error for object 0x10d930640:
pointer being freed was not allocated.
6. Interaction of readline with unix shell appears normal after call to
python terminates (both variants).
I have some information (file attached bu1.txt). I also attach the crash
report produced by Macos (bug2.txt).
I haven't yet collected any evidence for Point 2 above, but the fault
could perhaps be demonstrated using script.
What additional info would be helpful?
