STINNER Victor added the comment: I managed to reproduce the test_json crash on the "Fedora Stable ppc64le" buildbot using clang. Commands: --- ./configure --with-pydebug CC=clang make -j10 ./python -m test -v test_json --- I wrote GH-30972 to fix it. --

[issue40077] Convert static types to heap types: use PyType_FromSpec()

STINNER Victor added the comment: I marked bpo-23769 "valgrind reports leaks for test_zipimport" as duplicate of this issue. At exit, Python doesn't clear the static types of the _collections, itertools and _struct extensions: * itertools.accumulate * itertools.combinations *

[issue23769] valgrind reports leaks for test_zipimport

STINNER Victor added the comment: > valgrind reports leaks for test_zipimport It's not strictly a memory leak: running the same code multiple time doesn't leak memory. It's just that Python allocates memory once and never releases it (doesn't releast it at exit). --- leak4.py: Updated and

[issue46555] Unicode-mangled names refer inconsistently to constants

New submission from Kodiologist : I'm not sure if this is a bug, but it certainly surprised me. Most reserved words, when Unicode-mangled, as in "핕핖핗", act like ordinary identifiers (see e.g. bpo-46520). `True`, `False`, and `None` are weird in that Unicode-mangled versions of them refer to

[issue46554] Add append keyword argument to Path.write_text() and Path.write_bytes()

Barney Gale added the comment: >From https://stackoverflow.com/a/68969892 > I think a major reason why pathlib.Path objects don't (and, indeed, > shouldn't) have a append_text method is because it creates a hole for > inexperienced users to fall into, which is a huge sin in API design. >

[issue45113] [subinterpreters][C API] Add a new function to create PyStructSequence from Heap.

STINNER Victor added the comment: Raymond: > Is the subinterpreters work still on hold pending a PEP? While sub-interpreters is one motivation to convert static types to heap types, it's not the only one. IMO it's better to use the "embedded Python" use case to justify these changes, since
