[Bug target/29794] New: cc1 segfaults with -O3 -msched-control-spec

["tbm at cyrius dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I get the following segfault with -O3 -msched-control-spec on IA64.  While
this is completely repeatable, it doesn't happen when I call cc1 directly so
I cannot supply a backtrace.

With 4.2.0 20061022 I need to call -g -O3 -msched-control-spec to see this
while 4.2.0 20061107 requires -O3 -msched-control-spec.

Can someone confirm this bug?

tbm@coconut0:~$ /usr/lib/gcc-snapshot/bin/gcc -c -g -O3 -msched-control-spec
openbox-screen.i
gcc: Internal error: Segmentation fault (program cc1)
Please submit a full bug report.
