Hi,
I'm hitting an ICE with ifx version 2025.0.4 for long module/submodule names when the submodule is stored in a different file than the module. ifort has no issue for the same scenario.
Here is a reproducer. The module file is:
module a_very_long_module_name_will_cause_an_ice_at_compiler_time
implicit none
interface
module subroutine fct( Var )
implicit none
logical ,intent(in) :: Var
end subroutine
end interface
end module
and the submodule file is:
submodule(a_very_long_module_name_will_cause_an_ice_at_compiler_time) another_long_name_for_the_submodule
implicit none
contains
module procedure fct
end procedure
end submodule
The compilation is successful if the name of the module or the name of the submodule are shorten (for example to 'm' and 's'). Also, without altering the module/submodule names, if the submodule is placed in the same file than the module, then there is no compilation error, as in:
module a_very_long_module_name_will_cause_an_ice_at_compiler_time
implicit none
interface
module subroutine fct( Var )
implicit none
logical ,intent(in) :: Var
end subroutine
end interface
end module
submodule(a_very_long_module_name_will_cause_an_ice_at_compiler_time) another_long_name_for_the_submodule
implicit none
contains
module procedure fct
end procedure
end submodule
The ifx compilation was done using:
module load compiler/2025.0.4 --silent
ifx -v
ifx -c BugModule.F90
ifx -c BugSubModule.F90
which gives:
ifx version 2025.0.4

compilation aborted for BugSubModule.F90 (code 3)
The code compiles fine with ifort using:
module load compiler/2024.2.0 --silent
ifort -diag-disable=10448 -v
ifort -diag-disable=10448 -c BugModule.F90
ifort -diag-disable=10448 -c BugSubModule.F90
which creates the object files and outputs:
ifort version 2021.13.0
Thanks.

Same as https://community.intel.com/t5/Intel-Fortran-Compiler/2025-0-0-ICEs-with-long-module-submodule-names/m-p/1644241#M174275
I don't see any solution
