Compiling user code with intel fortan compiler and "-init=snan" triggers a segmentation fault

[pums974]

Compiling a user fortran code with ifort or ifx using the debug option "-init=snan" is triggering a segmentation fault at runtime

Even a very simple program is triggering this:

    PROGRAM HELLO_HDF

        USE HDF5, only: h5open_f, h5close_f, h5get_libversion_f, h5eprint_f

        IMPLICIT NONE

        INTEGER :: error
        INTEGER :: majnum, minnum, relnum

        CALL h5open_f(error)
        IF (error /= 0) then
            call h5eprint_f(error)
            ERROR STOP 1
        end if

        CALL h5get_libversion_f(majnum, minnum, relnum, error)
        IF (error /= 0) then
            call h5eprint_f(error)
            ERROR STOP 1
        end if

        CALL h5close_f(error)
        IF (error /= 0) then
            call h5eprint_f(error)
            ERROR STOP 1
        end if

        WRITE (*, '(" HELLO_HDF is linked with HDF5 Library version ")', advance="NO")
        WRITE (*, '(I0)', advance="NO") majnum
        WRITE (*, '(".")', advance="NO")
        WRITE (*, '(I0)', advance="NO") minnum
        WRITE (*, '(" release ")', advance="NO")
        WRITE (*, '(I0)') relnum

    END PROGRAM HELLO_HDF

I'm not experiencing this with hdf5 version 1.14.0 My OS is : Ubuntu 22.04.2 LTS

[derobins]

This is due to moving our floating-point type introspection to a run-time check instead of a compile-time check (to better support cross-compiling). After the 1.14.3 release, we added code that disables floating-point exceptions while we introspect the types.

Can you check if this behavior persists in the current develop branch?

[nncarlson]

We've hit the same problem with our Fortran code when exploring upgrading to 1.14 from 1.12. With Intel ifort and ifx "-init=snan" causes the problem as the OP reported. But more generally it happens if floating point exception trapping is enabled with any Fortran compiler: via the -fpe0 ifort and ifx flag, or the -ieee=nonstd option with the NAG compiler (which is the default!), or the -ffpe-trap=invalid gfortran flag. We've tentatively had to disable FP exception trapping, which makes us very uncomfortable. I hope this is a (very) temporary issue with HDF5.

Have you tried the latest develop or hdf5_1_14 branches? Those should have a fix for this.

[derobins]

Is this fixed w/ 1.14.4?

[nncarlson]

I tested with the 1.14.4-2 tar file and it appears to be fixed. I'm not sure why the 1.14.5 milestone was mentioned.
