optimization/8479: [new-ra] ICE in select_spill, at ra-colorize.c:1001

[Volker Reichelt]

The bug is still present in 3.3 branch and mainline.
A shorter testcase is the following:

-----------------------------------------------------------------------
int bar();

int foo()
{
    long double x=0, y=0;
    x += bar();
    return x+y;
}
-----------------------------------------------------------------------

Just compile with "gcc -fnew-ra -O -fPIC".

Regards,
Volker
