Too few data constants in initialization statement

Accelerated Computing HPC Compilers nvc, nvc++ and nvfortran
1

Hello. I am using:

$ nvfortran --version
nvfortran 21.9-0 64-bit target on x86-64 Linux -tp zen 
NVIDIA Compilers and Tools

Here is my test code:

$ cat shapelib.f90 
MODULE shapelib
  USE, INTRINSIC:: ISO_C_BINDING
  IMPLICIT NONE
  TYPE shpobject
     TYPE(c_ptr):: shpobject_orig = c_null_ptr
     INTEGER, POINTER:: panpartstart(:) => NULL()
  END TYPE shpobject
  TYPE(shpobject):: shpobject_null = shpobject(c_null_ptr, NULL())
END MODULE shapelib

Compilation gives an error:

$ nvfortran -c shapelib.f90 
NVFORTRAN-S-0066-Too few data constants in initialization statement (shapelib.f90: 8)
  0 inform,   0 warnings,   1 severes, 0 fatal for shapelib

I think the code is correct and this is a bug of the compiler. Would you corrrect this?
Sincerely.

Hi guez,

This was a known issue that was fixed in our 22.5 release. Please update your compiler to our latest release which you can download at: NVIDIA HPC SDK Current Release Downloads | NVIDIA Developer

Hello. Thank you. I have tried with a more recent version of your compiler and the compilation error on the test program above disappears, indeed.

However, I have the same compiler bug on a slightly more complicated version of the test (slightly closer to our real code):

$ nvfortran --version

nvfortran 23.1-0 64-bit target on x86-64 Linux -tp skylake-avx512

$ cat shapelib_2.f90
MODULE shapelib_2
  USE,INTRINSIC :: ISO_C_BINDING
  IMPLICIT NONE
  TYPE shpobject
     TYPE(c_ptr) :: shpobject_orig=c_null_ptr
     INTEGER,POINTER :: panpartstart(:)=>NULL()
     INTEGER,POINTER :: panparttype(:)=>NULL()
     INTEGER :: nvertices
  END TYPE shpobject
  TYPE(shpobject),PARAMETER :: shpobject_null = shpobject(c_null_ptr, &
       NULL(), NULL(), 0)
END MODULE shapelib_2

$ nvfortran -c shapelib_2.f90
NVFORTRAN-S-0066-Too few data constants in initialization statement (shapelib_2.f90: 10)
  0 inform,   0 warnings,   1 severes, 0 fatal for shapelib_2

So it seems the fix in version 22.5 was incomplete.

So it seems the fix in version 22.5 was incomplete.

Indeed. I was able to reproduce the error and have filed an issue report, TPR#34022. We’ll have engineering investigate.

Thanks!
