Bug #: 55595
Summary: [google] r172952 (LIPO) broke profiledbootstrap on
google/main, and later in google/gcc-4_7
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: middle-end
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: m...@use.net
starting with r172592, google/main fails profiledbootstrap with the error
below. going one revision back eliminates the error. later commits
compound/mutate the profiledbootstrap failures; once this bug is fixed, I'll
retest.
