Thread panicked while panicking

[Grinshpon]

If there is an error in the gamelisp script, chances are the whole program will panic, and then panic while panicking. I'm not totally sure why this happens yet.

It occurs while printing out a stack trace. Example:

unhandled error in run() call:

stack trace:
    glsp::call(), invoking (glhf:draw)
    (new-circle) at main.glsp:11

error: expected a [T; 2], received an array of length 3

Turns out I needed the the closure in runtime.run to take ownership of the context, because it's an rglobal. At least I believe that's what the problem was, because changing runtime.run(| | { ... to runtime.run(move | | { ... stopped the panics.
