I am experiencing a similar problem but I get a different error message. I am running OS 10.5 on a macbook pro. I was using sage2.10 and I didn't have this problem. Below is what I got after I upgraded to sage 3.0.
Thanks. ==== sage: plot(sin(x), (0,10)) sage.bin(395) malloc: *** error for object 0xa08c46d8: Non-aligned pointer being freed *** set a breakpoint in malloc_error_break to debug sage.bin(395) malloc: *** error for object 0xa08c46d8: Non-aligned pointer being freed *** set a breakpoint in malloc_error_break to debug sage.bin(395) malloc: *** error for object 0xa08c46d8: Non-aligned pointer being freed *** set a breakpoint in malloc_error_break to debug sage.bin(395) malloc: *** error for object 0xa08c46d8: Non-aligned pointer being freed *** set a breakpoint in malloc_error_break to debug (and a few dozen more identical lines follow.)
