https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D255445 Kai Knoblich <kai@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kai@FreeBSD.org --- Comment #12 from Kai Knoblich <kai@FreeBSD.org> --- Created attachment 224534 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D224534&action= =3Dedit python38-fix-threading-v1.patch At the outset: Thanks for the report and the detailed descriptions. The threading issue with Python 3.8 (tested with 3.8.9 from the Ports tree)= can be reproduced via the script from comment #2. Following vanilla releases of FreeBSD were tested: - 11.4-RELEASE-p9 [amd64/i386] - 12.2-RELEASE-p6 [amd64/i386] - 13.0-RELEASE-p0 [amd64] - 14.0-CURRENT main-n246037-ca6e1fa3ce8 [amd64] If the attached patch is used, which contains the two backported commits, as noted in comment #0 (BPO-19466 + BPO39511), the regression doesn't occur on= any platform listed above. A side note: If a VM has only one vCPU, the threading issue doesn't seem to= be reproducible with an unpatched version of Python 3.8.9. --=20 You are receiving this mail because: You are the assignee for the bug.=
