[Bug middle-end/41713] New: -O -flto -g: ICE in lto_output_tree_ref, at lto-streamer-out.c:732

[burnus at gcc dot gnu dot org]

$ gfortran -O -flto -g -c test.f
test.f: In function 'makenumberstring_':
test.f:8:0: internal compiler error: in lto_output_tree_ref, at
lto-streamer-out.c:732

That's with Rev. 152840 (and thus later then Rev. 152767 which fixed PR 41521).

Reduced testcase:

      FUNCTION makenumberstring(x)
      IMPLICIT NONE
      REAL, INTENT(IN)     :: x
      CHARACTER(len=20)      :: makenumberstring
      INTEGER             :: xx
      xx = x**2  ! << ICE
      makenumberstring = ''
      END FUNCTION

Confirmed.  Alex didn't update LTO with the introduction of DEBUG_EXPR_DECLs.
