In converting from 1.35 to 1.36 I ran into the following bug 
(on both sun3-os4 and sun4-os4):

ben31> more tmp.c
class t {
	int a;
public:
	void* operator new (long size) { return new char [size]; }
	void operator delete(void* p) {}
	t() {}
	~t() {}
};

ben32> g++ -v tmp.c
gcc version 1.36.0 (based on GCC 1.36)

My fault?

This is fixed in 1.36.2-.
