getting catastrophic error: **Internal compiler error: internal abort**

Hi all.
I found that the following simple code produces an internal abort in the more recent intel fortran compilers.


Using the compilers I have at hand, it compiles fine up to
- Intel(R) 64, Version 18.0.1.163 Build 20171018
It starts not compiling from
- Intel(R) 64, Version 19.0.3.199 Build 20190206

up to the latest
- Intel(R) 64, Version 2021.3.0 Build 20210609_000000

Here is the code:

 

 

 

      module mymodule
      type pop
      real(8)     , allocatable :: comp_1  (:)
      character(8), allocatable :: comp_2  (:, :)
      end type pop

      type(pop) :: aa

      end module mymodule

      program main
      use mymodule

      call sub1() 
      call sub2() 
      end program main

      subroutine sub2() 
      use mymodule
      print * 
      print *, allocated(aa%comp_1 ), aa%comp_1  
      print *, allocated(aa%comp_2 ), aa%comp_2 
      print * 
      end    


      subroutine sub1() 
      use mymodule
      allocate( aa%comp_1 ( 2 )      , source = 1.d0)
      allocate( aa%comp_2 ( 2 ,  2 ) , source = 'b       ')
      end    

 

 

 

 

Note that it also compiles fine with GNU Fortran (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2).

Did I miss some compiling option, possibly become mandatory in the latest intel fortran compiler version?
Otherwise it looks like a regression error.

EDIT
However, I found that the error does not happen if I do a two-steps-job, first using the "-c" option to compile-only, and then invoking the compiler using the object file as the input.
This way, I finally get an executable apparently working fine:

 

$ ./a.out
 
 T   1.00000000000000        1.00000000000000     
 T b       b       b       b       
 

 


Thanks!

GM

I filed a bug report on this, CMPLRIL0-34024.   

It compiles OK with ifort -O0 and with ifx at all opt levels.

I'll let you know its progress to a fix.

Good News! This Internal compiler error is fixed in the Fortran compiler 2021.4.0 that was released last week.


Can you try the new compiler and let me know how it works for you?

@e745200  I haven't heard from you that the fix is confirmed. I'll no longer be following this thread and closing the associated case.
