I've tried to reproduce the bug with your script, but couldn't get
anything to crash (VM is Debian Jessie i386 running on KVM with upstream
kernel 4.1.12). Does the crash happen before all sessions get
established?

Can you reliably reproduce the bug? If so can you please try with 4.3?
It contains ppp fixes not included in 4.1.12.
