Python 3.14 fails to build on hppa, error indicates stack overflow (false positive?) #139914
Description
The original report is https://bugs.gentoo.org/959416 - however, we are hitting this in Gentoo release engineering and it is blocking the update of the HPPA stages.
During Python 3.14 build, an error message indicating a stack overflow occurs on Linux/HPPA. Note that HPPA is an outlier in the sense that its stack grows UPwards, which makes me suspect that it could be a false positive.
The log snippet below is Python 3.14.0 in a qemu-hppa chroot; the log in the above bug is a prerelease on real hardware.
