   Please report this in   
   https://community.intel.com/t5/Intel-Fortran-Compiler/bd-p/fortran-compiler   
   and provide a reproducer. Internal Compiler Error is always a compiler   
   bug. But before you do, try ifx instead of ifort, as it has an entirely   
   different code generator and is the path forward for Intel. Bugs that   
   are ifort-only are unlikely to get fixed.
