gulp Segmentation fault: 11 and Abort trap: 6 OSX

We've been running on gulp with a set of tasks, with browser-sync and gulp.watch to reload the browser when files are changed. Increasingly I've been seeing more and more Segmentation fault: 11 and Abort trap: 6 intermittently on 2 different projects.

The gulp task layout is a derivative of this: https://github.com/notbrain/viceroy

I really have no idea where to start pinpointing the culprit besides whittling down the set of tasks to run until I run into the issue when only running a single task via watch and browser-sync.

So, this is mainly a plea for help if someone else has seen this issue

Abort trap 6 example

Segfault: 11 example:

[BS] File changed: build/views/sailingsSearchStep1.html
[BS] File changed: build/views/sailingsSearchStep2.html
[BS] File changed: build/views/sailingsSearchStep3Container.html
[BS] File changed: build/views/sailingsSearchStep3Weight.html
[BS] File changed: build/views/searchSubmitted.html
[BS] File changed: build/views/signup.html

[BS] File changed: build/views/signupStep2.html
[BS] File changed: build/views/signupStep3.html
Segmentation fault: 11

I've seen issues with similar end results when gulp-sass tried to parse empty .scss files, but we are using .less. Any guidance is greatly appreciated - while the project above is still usable, I have started another side project that has significantly fewer files but I see the Segfault: 11 bug so much that I'm considering a move to an npm script based workflow to work it out.
