[R] fit for truncated normal distribution

I see it in three different Mac builds, including a quite recent local R-devel build.
It boils down to this:
> dtruncnorm(numeric(0), mean=6.7, sd=1.38, a=-Inf, b=9)
Floating point exception: 8
which looks like a bug in the truncnorm package, where dtruncnorm() is unprepared for a zero-length argument.
(The indirect cause is fitdistrplus:::test1fun, which makes calls like the above.)
