This is an android-specific crash. It's a stack error, and the Android
stack is prickly.
0 $: y
is an instant infinite recursion. You wanted 0 u foo v y .

I'm sending this to beta, but it also happens in J903:
the following (attempt to a) ambivalent conjunction reliably crashes J on
android (64 bit):

+foo- 10 NB. + - are just for the sake of having arguments.
What does work fine is the dyadic application of the same:
10 +foo- 5

Likely my use of $: is off, but it shouldn't crash, no?
