I could reproduce this problem as well. I also tried to reduce the
issue. It is an ICE in GCC and I have made a small testcase which I am
able to reproduce on gcc-4_3-branch I have reported a gcc bug(PR36350)
for it  Meanwhile you can remove -frename-registers optimization pass
and ICE should go away.

Something like this might work around for glibc
