Bug ID: 115635
Summary: [15 regression] Bootstrap fails with failed self-test
(diagnostic-path.cc:1153: test_empty_path: FAIL:
ASSERT_FALSE ((path.interprocedural_p ())))
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
CC: dmalcolm at gcc dot gnu.org
Target Milestone: ---
I'll try to reproduce standalone outside of packaging later.
While I suspected diagnostic changes from a few days ago, I bootstrapped fine
just 6 hours or so ago. But hopefully it's something simpler than a
miscompilation. Will see.
