--- Comment #1 from janus at gcc dot gnu.org 2013-01-25 16:30:22 UTC ---
Confirmed. Fails with 4.6, 4.7 and trunk, while it works at least with 4.3.
Reduced/modified test case:
subroutine cchaine (i)
implicit none
integer :: i
character(len=i) :: chaine
write(*,*) chaine
end subroutine
Backtrace on trunk:
internal compiler error: in gfc_get_symbol_decl, at fortran/trans-decl.c:1441
subroutine cchaine (i)
