Remember `build-details.json` (PEP 739)? The file added to #CPython to support cross-compiling extensions?
Well, turns out it gets generated incorrectly when cross-compiling CPython itself 🤦. Let's see if I can fix that…
#Python

Zero days since I've discovered a random #CPython bug that triggers in very specific circumstances and I don't really have time to report it, nor can expect anyone to do it for me.
This time it's a test failure and refcounts being broken while running fastjsonschema's test suite on #Python 3.15 freethreading with pytest's --junit-xml option enabled 😱. And of course removing --junit-xml makes all tests pass.
EDIT: and of course I cannot reproduce outside Portage. Yet inside, it reliably crashes every single time.

Zero days since #CPython broke the extension ABI at the very last minute after asking everyone repeatedly to test prereleases. And of course they don't bother tracking ABI changes in any way, so they could at least give people heads up that important pieces of their system will start segfaulting after the upgrade. All they can offer is a knee-jerk response of "we never promised ABI stability".
And yes, this is a huge PITA for #Gentoo users who opted in to helping out.

#PSA to #Gentoo users: Please don't upgrade to #CPython 3.14.0b4, that release is borked and causes segfaults in random packages. I've just pushed a mask but warning in case you hit the upgrade before it reaches you. We'll investigate when we have more time.
