If you call on a ttc in the way you do it, then you will get entry
zero in the ttc. It works (in general), but since you do not actually
know what font you are using, it is not a wise thing to do :)
It is better to always use name: for fonts inside collections.

I think it crashes because the 'compose' feature is modifying the node
list directly, thus bypassing the 'does this glyph exist' test in the
engine itself (that test runs at node creation time). Without
'compose=yes' it does not crash, just does not show anything.
Hans and I have to discuss how to handle this (whether it should be
the engine or the lua side doing the existance test to prevent the
crash) but Hans is not online today so it will have to wait for a bit.
