--- Comment #3 from Mark Millard <markmi@dsl-only.net> ---
(In reply to Chris Collins from comment #0)

If you know adding some notes about the following
sorts of points it might help with folks that look
into this:

A) Are all the failures for compiling
   DataFormatters/TypeSummary.cpp ?

B) Does DataFormatters/TypeSummary.cpp
   sometimes compile okay (no Segmentation
   Fault)?

If the answer to (A) is "no" then questions
similar to (B) apply for the other failure
points.

I'll note that I had a context that was
analogous to (A): no with (B): yes and it
turned out that I had access to a system
that had its memory settings poorly
"optimized" (to the point of occasional
unreliability). Clang 4 seemed to show
this notably more than 3.9 did but it
was not clang's problem.

Of course I've no clue if such might apply
to your context. But it illustrates that
such additional notes can be helpful.
