--- Comment #5 from Markus Trippelsdorf <markus at trippelsdorf dot de> 2012-09-26 17:58:44 UTC ---
gcc-4.7 and 4.8 are also affected.

Reduced:

markus@x4 tmp % cat test.i
typedef struct
{
}
floatx80;
register struct CPUX86State *env asm ("ebp");
floatx80 float64_to_floatx80 (int, int);
typedef struct
{
    floatx80 d;
}
FPReg;
struct CPUX86State
{
    FPReg fpregs[0];
};
void
helper_fldl_ST0 ()
{
    env->fpregs[0].d = float64_to_floatx80 (0, 0);
}

markus@x4 tmp % gcc -mavx -m32 -c test.i
test.i: In function âhelper_fldl_ST0â:
test.i:20:1: internal compiler error: in dwarf2out_frame_debug_expr, at
