Repro steps

Build with this configuration :

 "optimization": true,
              "outputHashing": "none",
              "sourceMap": true,
              "extractCss": true,
              "namedChunks": false,
              "aot": true,
              "extractLicenses": true,
              "vendorChunk": true,
              "buildOptimizer": true,

Observed behavior

Blocking at 95% but folder and map exist on filesystem, cli never finish 95% step. (it works if disabled optimisation option)
95% emitting index-html-webpack-plugin

Desired behavior

Finish generation build with sourcemap when optimisation and buildOptimizer are enabled in configuration

update: same behavior in v6 release of angular&cli

Disabling sourceMaps seems to resolve the problem

If you set --optimization=false build can succeed with --source-map enabled
