Thanks for reporting. I haven't tried ifx in a while, and definitely not a recent version. I'll try it and let you know what I find.
Hi @aminiussi, I can't seem to reproduce this. Here's what I have:
$ ifx --version
ifx (IFX) 2023.2.0 20230721
Copyright (C) 1985-2023 Intel Corporation. All rights reserved.
HDF5 is 1.12.2 built with ifort-2021.6.
All tests pass on the latest main.
Similarly, all tests pass with ifort-2021.10.0 (that's the latest version released before deprecation in favor of ifx.
Hi @milancurcic,
The test in my build fails with "unmapped address" with the following stack trace:
6: 0 0x000000000004cb95 ucs_debug_print_backtrace() ???:0
6: 1 0x0000000000415d17 nf_maxpool2d_layer_mp_backward_() /scratch/alainm/view/neural-fortran/src/nf/nf_maxpool2d_layer_submodule.f90:107

The element of the backtrace is weird: /scratch/alainm/view/neural-fortran/src/nf/nf_layer_submodule.f90:0
as there is no code there.
We are using hdf5 1.14.1, and the underlying gfortran is 12.2.0. Appart from that, our ifx is slightly older...

Is that a parallel build and, if yes, which MPI is used ?
Thanks
I did a debug -check all build. The test is failing with:
forrtl: severe (408): fort: (3): Subscript #3 of the array MAXLOC_X has value 0 which is less than the lower bound of 1

Thank you, @aminiussi, this is very helpful and may be related to #145. It's possible that this is a bug that other compilers (and non-debug build modes) failed to catch but are producing incorrect results. I'll look deeper into this.
Is that a parallel build and, if yes, which MPI is used ?
I haven't built in parallel with the Intel compilers. It's Intel MPI that comes bundled with the OneAPI suite, but I don't think I configured it properly on my computer and haven't had time to dedicate to a parallel Intel build.
Hi,
Is ifx (intel nex generation fortran compiler that is replacing ifort) supported, I'm getting the following failures with ifx 2023.1.0:
On release build, these are failing on memory error.
In debug more, only test_optimizers is failing.
All this is on master
Thanks
