--- Comment #7 from Martin Liška <marxin at gcc dot gnu.org> ---
I tried to investigate:
gfortran ./gcc/testsuite/gfortran.dg/submodule_6.f08 -flto
If I compare corresponding argument passed to output_addr_const w/o LTO, I see:
(const_int 54796891 [0x344225b])
,instead of:
(mem/u/f/c:DI (symbol_ref/f:DI ("*.LC0") [flags 0x2] <var_decl 0x7fbb9b3d52d0
*.LC0>) [0 S8 A64])
Thus it looks for me that in case of LTO, it is unable to resolve offset of the
variable *.LC0:
<var_decl 0x7ffff6a2c2d0 *.LC0
type <pointer_type 0x7ffff6e23888
type <record_type 0x7ffff6e237e0 t_a BLK

I confirm the ICE for 4.8 up to trunk (6.0), but all the tests compiles in a
fraction of second.
