Hi, the below code causes a crash with ifort/ifx 2019+ including ifort (IFORT) 2021.1.2 20201208 and ifx (IFORT) 2021.1.2 Beta 20201214 $ cat bug.f90 module exception_callback public :: f_err_set_callback contains subroutine f_err_set_callback(callback) external :: callback end subroutine f_err_set_callback end module exception_callback module set_callback use exception_callback private public :: f_err_set_callback end module set_callback module main interface subroutine init() use set_callback end subroutine init end interface end module main end $ ifort bug.f90 bug.f90: catastrophic error: **Internal compiler error: segmentation violation signal raised** Please report this error along with the circumstances in which it occurred in a Software Problem Report.

Sorry, the formatting was messed up above. Here is the file again:

module exception_callback
  public :: f_err_set_callback
contains
  subroutine f_err_set_callback(callback)
    external :: callback
  end subroutine f_err_set_callback
end module exception_callback

module set_callback
   use exception_callback
   private
   public :: f_err_set_callback
end module set_callback

module main
  interface
     subroutine init()
       use set_callback
     end subroutine init
  end interface
end module main

end

[Arjen_Markus]

You probably already know that but ICEs (internal compiler errors) are always serious errors, independent of whether your code is correct or not.

[Bart_O_]

Note that there are at least two ways to workaround the issue:

1.

use the import statement and move the use to module scope like this:

module main
  use set_callback
  interface
     subroutine init()
       import set_callback
     end subroutine init
  end interface
end module main

or using the original module directly instead of the one that wraps it:

module main
  interface
     subroutine init()
       use exception_callback
     end subroutine init
  end interface
end module main

the second method worked well for BigDFT (viz. https://github.com/ComputeCanada/easybuild-easyconfigs/blob/computecanada-master/easybuild/easyconfi...  )

I'll open a bug report.  thanks for bringing this to our attention
