This failure reproduces for me with svn revision 177466 (2011-08-05), going
back at least as far as 2011-08-02. I'm on Ubuntu 10.10, x86-64.

cat >test.c <<EOF

  return (!si2 || (!si1 && si2)) ? si1 : (si1 % 3);
}
void func_65(int p_66) {
    g_78 = MOD(p_66, 3);
}
void func_54(int si1) {
    func_65(0);
    func_65(1);

This test case is reduced from the output of Csmith 2.1.0 (git hash 210eda7,
https://github.com/Quuxplusone/csmith/), using the following command line:
csmith --paranoid --no-longlong --no-pointers --no-arrays --no-jumps --consts
--no-volatiles --no-checksum --divs --muls --bitfields --packed-struct -s
