Halting Problem at 95%. Shows emitting as the action doing.

[tibinthomas]

I was hit by a problem like halting problem of truing machine while using the angular cli as follows.
My script : node --max_old_space_size=4096 ./node_modules/@angular/cli/bin/ng build -e=prod --prod --sourcemap --vendor-chunk=true --build-optimizer

Versions

Angular CLI: 1.7.3
Node: 9.8.0
OS: win32 x64
Angular: 5.2.8
... animations, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser
... platform-browser-dynamic, platform-server, router

@angular/cli: 1.7.3
@angular-devkit/build-optimizer: 0.3.2
@angular-devkit/core: 0.3.2
@angular-devkit/schematics: 0.3.2
@ngtools/json-schema: 1.2.0
@ngtools/webpack: 1.10.2
@schematics/angular: 0.3.2
@schematics/package-update: 0.3.2
typescript: 2.4.0
webpack-bundle-analyzer: 2.11.1

Repro steps

Use this script : node --max_old_space_size=4096 ./node_modules/@angular/cli/bin/ng build -e=prod --prod --sourcemap --vendor-chunk=true --build-optimizer --stats-json

• Apply the above script to any angular project.
• If we replace --scourcemap with --no-souecemap the problem will not comes.

Observed behavior

The program is running indefinitely.

Desired behavior

The program should halt to say if there is some error in the script.

Running into this as well on CLI 1.7.3 (Windows 10 x64, node 9.x). Prior version seem to work (cli 1.6.8). I think this may be related webpack/webpack#2908

I am experiencing this too with 1.7.3 on Windows 10. Build finishes normally if I remove --sourcemaps from parameters.

Duplicate of #6795 (sourcemap problem on 1.7.x)

PS: Actually the original issue was possibly another thing, but last month of comments refer to the same thing as this one.

same here in 6rc6 infite : 95% emitting index-html-webpack-plugin
with this config:

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

same problem if I set buildOptimizer to false!

ps: it working when set optimization to false 95% step if finish in 1 second

(version : nodejs10, npm6, win64, angular6rc5, cli6rc6)

Same issue here with Cli 6.0.0, I can only build if one of sourceMap or optimization is set to false.

Samesies on moving from 1.7.4 to 6 to get more control over sourcemaps etc. for CD. Windows 10.

[sluglit]

Same as #10591

[robport]

+1

[crunchyintheory]

+1, also having this problem when sourceMap is set to true

[genna]

I have the same issue when sourceMap = true on @angular/cli 6.0.3
It started to appear after @angular/cli 1.6.8 on Windows 10

On Mac it works great

[robport]

Please note, I get this problem on my PC, but not on my Macbook. A colleague has also seen this problem on a PC laptop. So it seems Windows specific,

having it on mac too now
