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

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

sorry for the late update - In reviewing older issues I found this report. This bug was fixed in oneapi 2021.4 last year. And I tested the latest ifort and ifx to confirm it's no longer causing Internal Compiler Error.
