"floating-point execptions" in vasp.5.4.1-gfortran

[M Dave]

Hello all,

I recently installed vasp5.4.1. on my xenon work station using gfortran.

After a completion of calculation,using vasp_std (checked with scf/relax/optic) the following Note appears.

Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL
Note: The following floating-point exceptions are signalling: IEEE_INVALID_FLAG IEEE_DENORMAL

What does this note indicate? Is it an error? Is that something to do with my compilation?

Following is my make.include

# Precompiler options
CPP_OPTIONS= -DMPI -DHOST=\"IFC91_ompi\" -DIFC \
-DCACHE_SIZE=4000 -Davoidalloc \
-DMPI_BLOCK=8000 -DscaLAPACK -Duse_collective \
-DnoAugXCmeta -Duse_bse_te \
-Duse_shmem -Dtbdyn

CPP = /usr/bin/cpp -P -traditional $*$(FUFFIX) >$*$(SUFFIX) $(CPP_OPTIONS)

FC = mpifort
FCL = mpifort

FREE = -ffree-form -ffree-line-length-none

LLIBS = $(SCALAPACK) $(LAPACK) $(BLAS)

OBJECTS_O1 += fft3dfurth.o fftw3d.o fftmpi.o fftmpiw.o chi.o
OBJECTS_O2 += fft3dlib.o

# For what used to be vasp.5.lib
CPP_LIB = $(CPP)
FC_LIB = $(FC)
CC_LIB = gcc
CFLAGS_LIB = -O
FFLAGS_LIB = -O1
FREE_LIB = $(FREE)

OBJECTS_LIB= linpack_double.o getshmem.o

# Normally no need to change this
SRCDIR = ../../src
BINDIR = ../../bin

Can anyone suggest and help?

Thank you
