! { dg-do compile }

! This tests the fix for PRs 26834, 25669 and 18803, in which

! shape information for the lbound and ubound intrinsics was not

! transferred to the scalarizer.  For this reason, an ICE would

! ensue, whenever these functions were used in temporaries.

!

! The tests are lifted from the PRs and some further checks are

! done to make sure that nothing is broken.

!

! This is PR26834
