Bug Description
I can consistently reproduce this with the Ubuntu 17.10 kernel. It never happens with a mainline 4.13.11 kernel built from source.
To reproduce:
1. clone https:/
2. ./configure && make -j8
3. ./out/Release/
cctest is sometimes killed, sometimes locks up the computer. When the computer is still usable, the following message is logged:
