Observed behavior

The following error is thrown on the browser console and on terminal:

    at ChildProcess.target.send (internal/child_process.js:554:16)
    at AngularCompilerPlugin._updateForkedTypeChecker (G:\projects\FIVE-STAR\node_modules\@ngtools\webpack\src\angular_compiler_plugin
.js:370:34)
    at Promise.resolve.then (G:\projects\FIVE-STAR\node_modules\@ngtools\webpack\src\angular_compiler_plugin.js:208:22)
    at process._tickCallback (internal/process/next_tick.js:109:7)```

Desired behavior

This error is occurring after upgrading to 1.5.0. The ng serve should detect changes and should serve seamlessly without any error.

@filipesilva Seems related to the many child_process dying issues we had.

@chandanch can you try with 1.5.4 please? We had a problem with a hardcoded memory limit in #8306 that's fixed by now.

@filipesilva I just upgraded to 1.6.0-rc.0 and it is not crashing anymore.

I updated today from v6.0.8 to v6.2.4 and I have this issue again.
On every other save the CLI crashes.

My upgrade:

@pmeems can you open a new issue with a reproduction please?

[pmeems]

I've created #12553
ng serve --aot seems to trigger the behavior.
