I'm trying to run an "as basic" build as possible, which includes building 
boost math as a library. There are a few other libraries which similarly 
have "optional" build libraries, I don't know how many of them by default 
are built (I believe MPI is the main library which isn't built by default).

mostly != all :P I haven't tried running the tests without the -j flag yet 
(stop on first error), so i don't know how many tests failed, and it's 
possible that multiple compile errors/crashes could be present in a single 
test. I don't have some "automatic terminate compiler on crash" script, so 
every compile error means I have to click the mouse (which is more than I 
want to).

The test log suggests there's some script for running tests with an error 
timeout, I'll try to see if I can get that working so I can get the full 
report.

I concur, it does appear to be a compiler problem.
