This is a known issue for those trying to develop high quality numeric
codes using the Intel Compiler Suite.

You must ask the Intel Compiler to conform to the C language standard
for floating-point
expression evaluation; via the "-fp-model precise" compiler switch.
By default, the Intel Compiler developers chose to ignore the C
language expression evaluation rules.  Presumably in hope for gains in
floating-point performance.


    CC="icc -fp-model precise" CXX="icpc -fp-model precise"
./configure --enable-cxx
    make check
