Bug ID: 62020
Summary: [4.10 regression] ICE in add_symbol_to_partition
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: rguenth at gcc dot gnu.org
Host: *-*-solaris2.1[01]
Target: *-*-solaris2.1[01]
Build: *-*-solaris2.1[01]
Between 20140725 (r213049) and 20140801 (r213453) occured a testsuite
regression
on Solaris (both sparc and x86, 32 and 64-bit):
FAIL: g++.dg/lto/20100302 cp_lto_20100302_0.o-cp_lto_20100302_1.o link, -flto
-fabi-version=2 (internal compiler error)
UNRESOLVED: g++.dg/lto/20100302 cp_lto_20100302_0.o-cp_lto_20100302_1.o execute
-flto -fabi-version=2
The failure boils down to
./lto1 -quiet -fwpa cp_lto_20100302_0.o cp_lto_20100302_1.o

I can attach the .o files if this helps.
