--- Comment #5 from Tobias Burnus <burnus at gcc dot gnu.org> --- Another data point. Running on the "-flto"-compiled object file $ build/gcc/lto1 -fwpa test.o fails with the ICE. However, using $ build/gcc/lto1 -flto test.o is successful both on the CentOS6 system and on gcc20. On the openSUSE system, either works flawlessly.
