Reduced source:
class A { void report(double d = (__extension__ ((union { unsigned __l 
__attribute__((__mode__(__SI__))); float __d; }) { __l: 0x7fc00000UL }).__d)); };

This seems to go into an infinite loop for me:   
-------------------------------------------------   
class A {   
    void report(double d   
		= (__extension__ ((union { unsigned __l __attribute__((__mode__(__SI__)));   
		    float __d; }) { __l: 0x7fc00000UL }).__d));   
};   
-------------------------------------------------   
Surprisingly, if report() is a global function, then the code compiles fine.   
   
Certainly qualifies as a mainline regression.
