Debugging libsass segfault in Ember app

I took a working project under Ember CLI 0.1.15 and pushed it to 0.2.2 and started getting a segmentation fault. By installing node-segfault-handler I was able to get some visibility into what was going on but not being very adept at reading these dumps I'm not taking much away from this other than it's clearly related to SASS compilation:

I'm using the ember-cli-sass addon (version 3.1.0) which works in other projects so i'm wondering how to proceed in debugging this. Any help would be greatly appreciated.
