get size of malloc'd object

[flaps at utcs.UUCP]

A way to get a sufficient alignment constant should be as follows:

union ALIGNED {
	char garbage0;
	unsigned char garbage1;
	short garbage2;
	int garbage3;
	unsigned garbage4;
	long garbage5;
	unsigned long garbage6;
	float garbage7;
	double garbage8;
};

(sorry if I've left out any)

Then you can use sizeof(ALIGNED) as the alignment constant.  Am I mistaken?
The problem is that this number might be greater than the actual
alignment constant, for example if a "double" has length 8 but only
needs quad-word alignment.
