Bug #: 52800
Summary: eglibc build broken with internal compiler error in
cfgloop .
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Keywords: ice-on-valid-code
Severity: normal
Priority: P3
Component: middle-end
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ramana@gcc.gnu.org
Host: x86_64-linux-gnu
Target: arm-linux-gnueabi
Build: x86_64-linux-gnu
eglibc builds broken with trunk on arm-linux-gnueabi with an internal compiler
error in cfgloop.c - it has happened in about the last 3 days or so since my
last successful build was on 27th March.
