Error when trying to test html5ever

[schumannd]

Hi,
I wanted to do some fuzzy testing on the Servo project, starting with html5ever.
So I tried setting afl.rs up according to the readme. But even if I just add the two dependencies, I get the following errors from cargo build:

failed to run custom build command for `afl-plugin v0.1.0`
Process didn't exit successfully: `/home/vagrant/html5ever/target/debug/build/afl-plugin-584d29624accb60e/build-script-build` (exit code: 101)

This was done in the vagrant VM provided by html5ever. So to reproduce:

• clone html5ever
• vagrant up (takes 1-2 hours)
• vagrant ssh
• add afl.rs as dependency
• build breaks with the above errors

Yes, thanks for pointing this out. LLVM was just upgraded in rustc a few days ago, and my code doesn't account for that upgrade. Will fix this shortly, thanks for the report!
