! Tests the fix for PR 31250
! CHARACTER lengths weren't reduced early enough for all checks of
! them to be meaningful.  Furthermore negative string lengths weren't
! dealt with correctly.
CHARACTER(len=0) :: c1   ! This is OK.
CHARACTER(len=-1) :: c2  ! { dg-warning "has negative length" }

CHARACTER(len=min(I,500)) :: c4  ! { dg-warning "has negative length" }
CHARACTER(len=max(I,500)) :: d1  ! no warning
CHARACTER(len=5) :: d2   ! no warning
