WRF 3.7 / catastrophic error: Internal compiler error: segmentation violation signal raised

Hi,

The following error has been reported by the compiler while compiling the file module_bl_temf.F (WRFV3/phys/module_bl_temf.F) from WRF V3.7 (http://www2.mmm.ucar.edu/wrf/src/WRFV3.7.TAR.gz) model for Intel MIC (configure option 17).

Please try a newer compiler.

Please try a newer compiler. 15.0.3 is current.

It fails on the -O3

It fails on the -O3 optimization, run the compile using -O3 and then change to -O2 in configure.wrf and compile the rest with that. Or update your compiler.

It would help quite a bit if

It would help quite a bit if one of you WRF users posted the machine-generated source file (module_bl_temf.f90, the attempted compilation of which caused the ICE), plus any required INCLUDEd files. Without that being available, the task of assembling a matching environment (OS, tools, system header files, compiler, libraries, MPI setup) is so big and the number of variations so numerous that mere reproducing of the ICE becomes a big project, so you will have to rely entirely upon other WRF users.

Hi,

Hi,

I have attached the machine generated source file. Please have a look at it.

Well, IFort 15.0.4-32-bit

Well, IFort 15.0.4-32-bit compiled the file module_bl_temf.f90 with no errors on Windows with the default option (/fast /MD) and also with /O3.

The 64-bit compiler did fine with /O2, but was taking an inordinately long time with /O3, so I aborted the run. It may be worth trying to compile the file on Linux using the current version of IFort.
