You should ask this on R-devel, and tell them exactly what compilers you
used. See the posting guide: this falls under
'Questions likely to prompt discussion unintelligible to non-programmers
should go to to R-devel.'
But yes, it is something to worry about and it looks as if your compiler
generated incorrect code. The 'R Installation and Administration Guide'
has things to say about what that compiler appears to be, and you seem
not to have followed its advice.

Hi,
After building R 2.14.1 on a Linux system (SUSE Linux Enterprise Server
11 (x86_64) ), I ran "make check" but it halted with the foll error:
Testing examples for package âbaseâ
Error: testing 'base' failed
Execution halted
I looked in <build dir>/test/Examples/base-Ex.Rout.fail and found the foll:

Error: !identical(0, -0, num.eq = FALSE) is not TRUE

I configured the R build with
./configure --prefix=/usr/local/packages/R/builds/2.14.1
--with-blas="-mkl=sequential" --with-lapack="-mkl=sequential" CC=icc
CFLAGS="-O3 -mkl=sequential" F77=ifort FFLAGS="-O3 -mkl=sequential"
CXX=icpc CXXFLAGS="-O3 -mkl=sequential" FC=ifort FCFLAGS="-O3
-mkl=sequential" LDFLAGS="-O3 -mkl=sequential"
I also tried building with O2 intead of O3, it gave the same error on
running "make check".
I had previously built R 2.11.1 similarly on the same system, and that
build passed all tests.
Is this error sth to be concerned with? If yes, how to fix it?
Many thanks in advance for the help
