Dear Berwin,

thanks a lot for the report!

  ((well, well ... you could also compile later versions.  It was
"only"  'make check' that failed ..))

  [yes, that was the bug; see below]

It is not a problem on 64-bit I think.  This is related to the
bug and bugfix  for PR#17274 
   ( https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17274 )
which I had handled.

Now I see the above, I can well imagine that I had made
assumptions that only worked on my (64-bit) platform.
I'll have a look and will amend the bug fix to also work on
"smaller" platforms - hopefully today.

[Rd] Problem compiling R patched and R devel on Ubuntu

[Berwin A Turlach]

G'day all,

since about a week my daily re-compilations of R patched and R devel
are falling over, i.e. they stop with an error during "make
check" (while building the 32 bit architecture) on my Ubuntu 16.04.3
LTS machine.  Specifically, a test in graphics-Ex.R seems to fail and
the last lines of graphics-ex.Rout.fail are:

  > ## Extreme outliers; the "FD" rule would take very large number of
  'breaks': 
  > XXL <- c(1:9, c(-1,1)*1e300)
  > hh <- hist(XXL, "FD") # did not work in R <= 3.4.1; now gives
  warning 
  Warning in hist.default(XXL, "FD") :
'breaks = 4.44796e+299' is too large and set to 1e9
  Error in pretty.default(range(x), n = breaks, min.n = 1) : 
cannot allocate vector of length 11
  Calls: hist -> hist.default -> pretty -> pretty.default
  Execution halted

My R 3.4.1 installation, the last R patched version that I could
compile (R version 3.4.1 Patched (2017-07-26 r72974)) and the last R
devel version that I could compile (R Under development (unstable)
(2017-07-26 r72974)) give the following results (under the 32bit
architecture and the 64bit architecture):

  > XXL <- c(1:9, c(-1,1)*1e300)
  > hh <- hist(XXL, "FD")
  Error in pretty.default(range(x), n = breaks, min.n = 1) : 
invalid 'n' argument
  In addition: Warning message:
  In pretty.default(range(x), n = breaks, min.n = 1) :
NAs introduced by coercion to integer range

Not sure if this is a general problem, or only a problem on my machine.

Cheers,

Berwin
