A gcc build from svn today (20091228) gets an ICE on the following code when
using -flto and -fsigned-char:

char *foo;
int main()
{
        foo = "bar";
}

# /gcc-test/bin/gcc -flto -fsigned-char foo.c
In function 'main':
lto1: error: type mismatch in address expression
<unnamed-unsigned:8> *

<unnamed-signed:8>

foo = &"bar"[0];

lto1: internal compiler error: verify_stmts failed


It passes with either option on its own.
