Test file "one2.ii"
For the big program, it is surely a regression and the code is (should be)
valid. I am less sure about the reduced test case.
Reproduce:
$ g++ -flto -w -O2 -c one2.ii two.ii
$ .../libexec/gcc/x86_64-unknown-linux-gnu/5.0.0/lto1 -quiet -o /dev/null
one2.o two.o -O2
two.ii: In function âvalidateâ:
two.ii:85:1: internal compiler error: in ipa_intraprocedural_devirtualization,
at ipa-prop.c:2611
validate ()
