Thank you for the feedback.

Looks like the summary is: Pseudo crashes on ARM hosts (but not on x86-
64 hosts).

Is it possible to get this file
/srv/pokybuild/yocto-worker/oe-selftest-armhost/build/build-st-
273901/tmp/work/cortexa57-poky-linux/cmake-example-
clang/1.0/pseudo//pseudo.log ?


Relevant section from the logs is:
