Note that a) r-base 0.90 compiled fine (since then we used to require Atlas
to build, so that never happened on too many archs, now re-designed) abd b)
R has a gazillion other regression tests that would fail.
I suspect it is either the src/nmath/bessel* code, or its interaction with
libc. Recall that the segment which failed passed NaN, NaN around as
