Bug#906085: gcc-8: 2 simultaneous threads of compilation cause machine shutdown

[Arthur Marsh <arthur.marsh@internode.on.net>]

Hi, it appears that the symptoms were caused by running the build under a kernel revision (between 4.18.0-rc8 and 4.18.0) that had issues.

Apologies for the trouble. 

Please close the bug report.

While gcc may use the system in unusual ways, it does not have the
permissions to shutdown a system.

If a user space program breaks a system, it is either a broken kernel or
broken hardware.

 -- System Information:

buster and oldstable?  This policy makes no sense.

 Kernel: Linux 4.18.0+ (SMP w/2 CPU cores; PREEMPT)

I don't think we have unreleased kernels in Debian.  You may want to
re-chekc this using a released version.
