--- Comment #1 from Gary Funck <gary at intrepid dot com> ---
We're seeing this as a bootstrap failure in libitm, built with checks enabled
and both host and target compilation flags set to -O0. We do not see the ICE
when compiled at -O3 and --enable-checking=release. This is based on GCC trunk
version 226170.
