VS watch somtimes cannot show member variable.

I am using VS2026+oneapi2025.3.1. Here is the code

module BBB implicit none type B integer :: ccc=1 real(8) :: ddd=2 end type B end module BBB module A use BBB implicit none type AA character(len=100) :: title="" type(B) :: bb contains procedure,pass :: setB end type AA interface module subroutine setB(self) class(AA),intent(inout) :: self end subroutine setB end interface contains module subroutine setB(self) class(AA),intent(inout) :: self self%bb%ccc=2 self%bb%ddd=4.0 end subroutine setB end module A program Console1 use A implicit none type(AA) :: ab call ab%setB() print *, 'Hello World' end program Console1

I can not see the member variable of "self%bb" that is “ccc" and "ddd", like following

I tried your program in the VS 2022 with the latest IFX, I could single step through all of the code and watch as the values changed.

The 1 and 2 changed to 2 and 4.

You may try it again without VS extension Intel® Fortran Expression Evaluator. The latest OneAPI HPC Toolkit does not include FEE, so I think it should work without FEE.

I only install VS the latest and oneapi the latest and it always has FEE and you can download FEE for free and install same.

As shown

Reinstall vs 2022 and select everything in the boxes, then install oneapi, make sure you delete everything first and then it might work. Of course you can look up the minimum VS boxes, there are lots of notes about that around, but mine just copies it from the last install.

Check your extensions. If you are using anything else I cannot help.

A direct upgrade from an older version of the HPC Toolkit will not remove the FEE. However, if you uninstall the older version of the HPC Toolkit first and then install the new version, the FEE will not be installed automatically. In my case, I completely uninstalled VS2022 and the HPC Toolkit first, then reinstalled VS2026 along with the latest version of the HPC Toolkit. The FEE was not installed automatically in this scenario. Should I roll back to VS2022?

Use the extensions manager in VS 2022 to find and load the FEE. Look for manage extensions.

But I have never loaded FEE, it is always installed when I load OneAPI as I do that on a lot of machines. There are five on my desk with it on.
