hanging process
After ~100M iterations I decided to shut down (ctrl-c).
go-fuzz shut down but one cpu remained at 100%. In htop, I saw an executable in /tmp consuming 100%; since the path contained go and I wasn't running anything else go-related at the time, I'm confident it's something spawned by go-fuzz.
I tried SIGSEGV, hoping for a core, but that did not stop it. After a bit I tried SIGTERM, which did stop it.
If I see this again, any suggestions on finding the problem?
If you see this again, try sending SIGABRT.
Then attaching with gdb and sampling stacks of all threads.
Also perf record -p PID on the process can shed some light as to what it's doing.
Also parent/child processes in ps afxu output.
