This looks like python itself is segfaulting, even without pseudo loaded
so it could well be something outside our control :/. Which python
version is that?

If you still have the build around it would be interesting to see if
just removing the cache directory fixed that or trying to narrow down
which files are triggering the segfault.

Likely, some of the changes in master meant the sstate checksums were
invalidated and it therefore required a rebuild. The sstate files are
only used if the checksums are found to be valid.
