[R-SIG-Mac] quantile() bus error

[Jennifer Small]

Hello list,

I'm attempting to build R 2.3.1 from source on a Mac Mini intel duo  
core with OS 10.4.7.  There were no errors reported in configure or  
make. However, make check fails immediately on the quantile function.  
The trace is

 > x <- sort(rnorm(100));  cH <- 1.35
 > pmin(cH, quantile(x)) # no names

*** caught bus error ***
address 0x107bcb1, cause 'non-existent physical address'

Traceback:
1: sort(x, partial = unique(c(lo, hi)))
2: quantile.default(x)
3: quantile(x)
4: pmin(cH, quantile(x))
aborting ...

If I open an R command line session and try to call quantile() I get  
the same bus error:

 > quantile(1:10)

*** caught bus error ***
address 0x107bcb1, cause 'non-existent physical address'

Traceback:
1: sort(x, partial = unique(c(lo, hi)))
2: quantile.default(1:10)
3: quantile(1:10)

Possible actions:
1: abort (with core dump)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace
Selection: q
Selection: 1
aborting ...
Bus error

I'm stumped. Any ideas? Thanks in advance.
