Bug ID: 63834
Summary: [5 Regression] unrecognised __has_attribute(xxxx) test
causes segv (prevents bootstrap on darwin12).
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: blocker
Priority: P3
Component: preprocessor
Assignee: unassigned at gcc dot gnu.org
Reporter: iains at gcc dot gnu.org

Test header
The changes at r217292 have introduced a segv for the attached testcase.
AFAICT the code is valid, this is used in a key system header on x86-64-darwin
so is a bootstrap blocker. Fails at stage#2 because libiberty's config.h
contains nonsense.
