! { 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
