Firefox also fails during the last libxul link of an lto/profiled build:

I've reduced this error with delta & C-reduce:

double sin ();
speex_resampler_init_frac ()
{
    a = sin (0);
}

typedef double UnaryFunType (double);
class A
{
public:
    int hash ();
    double lookup (UnaryFunType p1)
    {
        int a = hash ();
        if (p1)
            return 0;
    }
};
A b;
void
math_sin_impl ()
{
    b.lookup (sin);
}

Here is another example (this one triggers the same gcc_assert as in HJ's 
regression report):

markus@x4 moz_lto_debug % < test.i
float a;
double sin ();
update_filter ()
{
    a = sin (0);
}

markus@x4 moz_lto_debug % < test.ii
extern "C" double sin (double);
typedef double (*UnaryFunType) (double);
class A
{
public:
    int hash ();
    void lookup (UnaryFunType p1)
    {
        int a = hash ();
        p1 (0);
    }
};
A b, c;
void
math_sin_impl ()
{
    b.lookup (sin);
}

void
js_math_sqrt ()
{
    c.lookup (0);
}

markus@x4 moz_lto_debug % gcc -o test.o -c -flto test.i
markus@x4 moz_lto_debug % g++ -r -nostdlib test.o test.ii -flto -O2

Thanks. This fixes lto/profiledbootstrap.
