Tested revisions:
r163921 - crash
r153685 - crash
4.4 r160770 - warns
4.4 r149995 - warns

the 4.4 warning looks like:
cc1plus: note: -freorder-blocks-and-partition does not work with exceptions

The original testcase (comment #0) fails in 4.4 r160770 with:
$ CC=/mnt/svn/gcc-4_4/binary-160770-checking-yes/bin/gcc
$ $CC -O -fschedule-insns -fselective-scheduling -freorder-blocks-and-partition
-fprofile-generate
/mnt/svn/gcc-trunk/gcc/testsuite/gcc.dg/tree-prof/update-cunroll-2.c
$ rm *.gcda
$ ./a.out
$ $CC -O -fschedule-insns -fselective-scheduling -freorder-blocks-and-partition
-fprofile-use
/mnt/svn/gcc-trunk/gcc/testsuite/gcc.dg/tree-prof/update-cunroll-2.c
/tmp/ccHCIjjf.s: Assembler messages:
/tmp/ccHCIjjf.s:37: Error: .cfi_endproc without corresponding .cfi_startproc
/tmp/ccHCIjjf.s:53: Error: previous CFI entry not closed (missing .cfi_endproc)

I don't know if this PR is a regression or not.
