Summary: bootstrap fails on 4.8 and google/4.8 branch on
RHEL6.1 platform
Product: gcc
Version: 4.8.1

I'm getting this failure when trying to bootstrap on RHEL6.1, with either the
system compiler (gcc 4.4.x) or a 4.7-based compiler I bootstrapped successfully
before:

the problem is this line in dbgcnt.def:
DEBUG_COUNTER (clone)
unless there's a better suggestion, I'll attach a patch that renames the
counter to clone_function.
