re PR debug/84645 (-flto -g0 at compile-time vs. -flto -g at link time ICEs in add_dwarf_attr, at dwarf2out.c:4353)
2018-03-01 Richard Biener <rguenther@suse.de>
PR debug/84645
* dwarf2out.c (gen_variable_die): Properly handle late VLA
type annotation with LTO when debug was disabled at compile-time.
* gfortran.dg/lto/pr84645_0.f90: New testcase.
