	Your system manager is probably on the right track: the problem
	keeps coming up (is there an FAQ?). Michael Shapiro 'posted'
	a fix to the memory allocation routines in alloc.c:
	The error occurs when these routines are asked for 0 bytes of
	memory, so if you change that to 1 (or something like that),
	things should work fine.
