Created attachment 862792 [details] build log I'm no longer able to compile Cython with Python 3.10 since the bump to 0.29.34 (0.29.33 compiles fine) due to a [Errno 12] Cannot allocate memory (note that I have 16GB RAM and Cython does not even come close to using this much as per htop). emerge --info Portage 3.0.44 (python 3.10.11-final-0,

> DISTDIR="/dev/shm/distfiles" > PKGDIR="/dev/shm/binpkgs" > PORTAGE_TMPDIR="/dev/shm" Please do not use /dev/shm as temporary storage. It is meant to be used only by libc for shared-memory functions like shm_open().
Please try building cython with a more sane PORTAGE_TMPDIR / DISTDIR / PKGDIR. You should probably also clear out the contents of /dev/shm. If you still experience the issue, please re-open the bug report.
Apologies I was not aware of this, switching to the default DISTDIR="/dev/cache/distfiles" PKGDIR="/var/cache/binpkgs" PORTAGE_TMPDIR="/var/tmp" so that compilation takes place on disk (and clearing out /dev/shm) the issue persists (see build log attached).

Thanks for testing.
The compiler failure resolved itself when I rebuilt the python deps whilst upgrading to Python 3.11 from Python 3.10.
