Don't really know much about clang but following instructions here:

https://github.com/phpv8/v8js/blob/master/README.Linux.md

On Mac OSX with Vagrant (Virtualbox) on Debian jessie.

Didn't even know I had to do sudo apt-get install clang for the instructions to
work.

Anyway, got to this part of the instructions

make native library=shared -j8

which took forever (more than 15 minutes) then got the note to file a bug report

Hi Chris,

Thanks for taking the time to file a bug report! A couple of things.

  1. Please can you also upload the reproducer .c/.i file that the crash reporter will have produced alongside the .sh file that you uploaded. We can't reproduce without that.
  2. From the crash dump line here:

clang: error: unable to execute command: Killed

     it looks possible that this is not a clang error but your host OS killing the running cc1 process. If that's the case, we won't be able to reproduce and you'll need to sort out your host OS - you say it's Vagrant, so perhaps checking how much memory you gave it would be useful?

  3. Clang identifies itself as 3.8.0 which means it's a trunk version. That means it's unstable and that version is not tested, so you could have found a duplicate of an existing bug.

Cheers,

James
