ifx Internal Compiler Error with -heap-arrays option

I’m compiling a library, https://github.com/lauvergn/AD_dnSVM (see the zip file) and I’m getting an Internal Compiler Error when I’m using the  -heap-arrays option with ifx. 

The following combinations (ifx/ifort -O/-O0 …) give:

ifx -O -heap-arrays : ICE (error #5633: **Internal compiler error) while compilling SRC/ADdnSVM/dnVec_m.f90

ifx -O0 -heap-arrays : Compilation OK, execution ERR (on the Test_dnS.x test)

ifort -O -heap-arrays : Compilation + execution OK

ifort -O0 -heap-arrays : Compilation + execution OK

ifx -O : Compilation + execution OK

ifx -O0 : Compilation + execution OK

ifort -O : Compilation + execution OK

ifort -O0 : Compilation + execution OK

To reproduce the errors:

make FC=ifx OPT=1 ut

or

make FC=ifx OPT=0 ut

I’ve tried to reduce the library size without success.

Thanks

PS: I'm using the Intel Fortran Compiler (IFX) version 2023.1.0 (I don’t have access to a more recent version) on a linux distribution.

Thanks

I'm afraid, the problem with the **heap-arrays** option is still present with the version 2024.2.1 (20240711).

However, the error is only at the execution. There is no more "Internal Compiler Error":

ifx -O -heap-arrays : Compilation OK, execution ERR (on the Test_dnS.x test)

ifx -O0 -heap-arrays : Compilation OK, execution ERR (on the Test_dnS.x test)

Remarks:

- the errors in Test_dnS.x are not at the same line with the option -O and -O0

- With ifort, everything is running fine.

@lauvergn

just a clarification. By execution error you are referring to the unit tests that are run after compilation automatically by make?

[lauvergn]

Yes. I've got an error during the run of the first test just after the compilation.

The first executable is: Test_dnS.x

Great. Thanks, I'll wait for this version.
