On ubuntu-14.04 I'm seeing SIGABRT in couple do_install tasks even after reverting both pseudo changes (the upgrade from Alex as well as SRCREV bump to latest commit from Seebs).
So there might be different root cause for SIGABRT unrelated to pseudo which I haven't seen before, because pseudo locked-up in never ending loop before it reached that point. I kind of suspect the icecc changes as nothing else in last oe-core upgrade looked suspicious to cause such issues in unrelated components (like tzdata, update-rc.d do_install).
On ubuntu-18.04 with both changes included I've reproduced the lock-up and endless 100% CPU spin without pseudo.log growing in size.
I'll try to revert icecc changes to verify if it makes SIGABRT go away, then will try to upgrade pseudo again on 14.04 to see if it will spin or not.
