Bug ID: 65361
Summary: [5 Regression] LTO: tree check: expected tree that
contains ‘decl minimal’ structure, have ‘tree_binfo’
in add_type_duplicate, at ipa-devirt.c:1509
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto

Follow up to PR65276, PR65302 and PR65316, still for the same program - but I
have the feeling, we are slowly getting there. The real-program's message is
slightly different (get_odr_type, at ipa-devirt.c:1704).
g++ -c -std=c++11 -flto -O2 two.ii one.ii
gcc -r -nostdlib two.o one.o

polymorphic bases is defined in another translation unit
