After a gargantuan effort updating our entire codebase to Swift 3.0, we are now
being greeted with "Segmentation fault: 11" compiler crash whenever attempting
to build.
The issue seems to be related to generics, and sounds similar to this issue:

I've filed a bug report that includes our project codebase, which triggers the
issue 100% of the time:
rdar://problem/28890409
The usual work-around of turning off Whole Module Optimization (which has
gotten around a lot of compiler crashes in the past) does not work here.
Unfortunately, this code is in such a tangle of generics that undoing it is not
going to be simple. Until a new version of Xcode ships, we're pretty much
blocked from using Swift 3.0 unless another work-around is possible.
