The tree dump shows that the argument x is never used in the string allocation. A longer testcase, including SAVE (which seems also mishandled, but it is probably linked to this issue): program test logical :: L L = g(1) write(*,*) L L = g(2) write(*,*) L contains logical function g(x) integer :: x character(len=x), allocatable :: s save if(.NOT.allocated(s)) then allocate(s) g = .FALSE. else g = .TRUE. end if write(*,*) len(s) end function g end ^ permalink raw reply [flat|nested] 6+ messages in thread
