Same here but for me it happens very frequently.
Steps to reproduce:

1. ng new myApp
2. ng serve --open
3. Change any file and save

Same error:

webpack: Failed to compile.

Only difference is that It's every two or three saves. Some times I get another error:

[stefanKuijers]

Could it be related to this issue?

Tried with Yarn and NPM (both new projects) but same results.

[stefanKuijers]

I updated my node to v8.9.1 and I don;'t have the problem any more.

Fixed for me!

[filipesilva]

#8090 together with #8646 should have fixed this problem generally.
