I have bootstrapped revision r240599 with the patch
https://gcc.gnu.org/ml/gcc-patches/2016-08/msg01315.html without any problem.
However compiling the following Fortran tests
FAIL: gfortran.dg/binding_label_tests_16.f03 -g (internal compiler error)
FAIL: gfortran.dg/module_commons_3.f90 -g (internal compiler error)
FAIL: gfortran.dg/module_equivalence_1.f90 -g (internal compiler error)
FAIL: gfortran.dg/use_11.f90 -g (internal compiler error)
FAIL: gfortran.dg/use_only_1.f90 -g (internal compiler error)
FAIL: gfortran.dg/widechar_5.f90 -g (internal compiler error)
FAIL: libgomp.fortran/udr15.f90 -g (internal compiler error)
are giving an ICE with -g of the kind
internal compiler error: in dwarf2out_imported_module_or_decl, at
dwarf2out.c:24070
corresponding to
gcc_assert (scope_die->die_child);
The Ada test gnat.dg/debug7.adb is also failing with
FAIL: gnat.dg/debug7.adb (test for excess errors)
Excess errors:
gnat1: incorrect object file extension
