Hi,
Here is a minimal reproducible example (MRE) for some code which generates an ICE due to the length of the name of the module and sub-module exceeding the internal buffer inside ifort.
Module A_Very_Long_Module_Name_Composed_Of_Many_Characters
implicit none
interface
module subroutine DoSomething()
end subroutine
end interface
End Module
SubModule(A_Very_Long_Module_Name_Composed_Of_Many_Characters) A_Long_Submodule_Composed_Name_Of_Many_Char
implicit none
contains
module procedure DoSomething
end procedure
End SubModule
Compiling this code using:
module load --silent compiler/latest
ifort --version
ifort Main.F90 -c
gives
ifort (IFORT) 2021.5.0 20211109
Copyright (C) 1985-2021 Intel Corporation. All rights reserved.
Main.F90: catastrophic error: **Internal compiler error: Creating this name exceeds internal buffer: a_very_long_module_name_composed_of_many_characters@a_long_submodule_composed_name_of_many_char._
compilation aborted for Main.F90 (code 1)
If the name of the sub-module is shorten by a single character (for example, by removing the final "r" letter) the compilation succeeds. It seems that a maximum length of 96 character is used internally by ifort for the combined length of a module and sub-module.
Would it be possible to increase this number of a higher value in the nest release of the compiler?
The motivation for this request if the following. In our real case scenario we are using some code generation techniques to automatically create module/sub-module names. So, we don't have (an easy) control on the length for these names and, in some cases, these names can be quite lengthy.
Thank you.
