some xblas file compilation using ifort 14.0 is super slow

Just switch from ifort 12.1 to ifort 14.0, and trying to build xblas library, the compilation gets stuck on several files.

For example, xblas/src/gbmv2/BLAS_zgbmv2_c_z_x.c will get stuck, and never completed for several hours:
/opt/intel/composer_xe_2013_sp1.0.080/bin/ia32/icc -I/Ydir/savesets/v750/s -I. -I/Ydir/savesets/v750/s/xblas/src -c -fPIC -DGT_DOUBLE_PRECISION -DGTDOUBLE -DCONFIG_FC_UNDERSCORE -DCONFIG_FC_RETURNS_DBL_REAL -O2 -Dlinux -D_ALL_UNIX_  -DGNUC3 -DINTEL_IA32 -o COMMON/obj/BLAS_zgbmv2_c_z_x.o /Ydir/savesets/v750/s/xblas/src/gbmv2/BLAS_zgbmv2_c_z_x.c

There are at least 4 such files in the xblas having similar issue.

I do not think I have seen this using ifort 12.1.

Anyone have similar experience? and hopefully work around?

I know someone will advice me to use mkl, but the build is targetting realtime system, I do not want to link with MKL.

It looks like you are compiling a C program - you might have better luck asking this question in the Intel C/C++ forum.
