Bug ID: 64023
Summary: [5 Regression] r216964 breaks bootstrap on darwin when
using gcc as the bootstrap compiler.
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: dominiq at lps dot ens.fr
CC: fxcoudert at gcc dot gnu.org, howarth at bromo dot med.uc.edu,
iains at gcc dot gnu.org, jakub at redhat dot com
Host: x86_64-apple-darwin*
Target: x86_64-apple-darwin*
