I was working on an earlier version of this tweetcart when I noticed a problem with ord used to poke in a single call (i.e. the three-parameter version).

The relevant portion:

--rest of the cart

On my Mac, at least, I got:

pico8(36303,0x10ab435c0) malloc: Incorrect checksum for freed object 0x7fca4d589600: probably modified after being freed.
Corrupt value: 0x3deadbeef
pico8(36303,0x10ab435c0) malloc: *** set a breakpoint in malloc_error_break to debug

I was able to reproduce it without such a strange byte-string too, and I can almost imagine what the offending code is doing.

oh, on windows it even funnier... it runs fist, but than crash randomly at any other point, for example when you try to switch to the editor with esc.
