c++: internal compiler error: Killed (program cc1plus)

got another error from cmake

again the question... is this error related to e.g. the custom gcc for the vm? or is it a temporary hhvm dev version error?

[javer]

I've seen this error many times, every time it appears on another file and line. It is fixed by restarting make after login to the VM. When I used only 2 cores this error appears very rare, but compiling takes 2x time.

Another thing is to use gcc 4.8.2, someone wrote that it will fix this issue.

[staabm]

I will try to use gcc 4.8.2..

Anything more we could do to reduce compile time? Maybe some parallelism?

[javer]

I think there is no need to think about ways to speed up compilation as it is performed only once in a few days. Also instead of rebuilding VM from scratch we can login into existing VM, update HHVM sources from git and run cmake and make.

upgrading to gcc4.8 and stepping down to -j4 on Ubuntu 12.04 LTS solved this issue for me

Thanks @shivaas
