[Bug-apl] Calling a function and assigning result corrupts result

[Elias Mårtenson]

This one is hard to explain, so I was about to attach a workspace that reproduces the error.

However... As I tried to do a )SAVE to save the workspace, the interpreter crashed and of course I was editing functions directly in the workspace so they weren't saved. I'll rewrite it so I can show you.

For now, take a look at the crash report:

Assertion failed: sub_idx < values.size()
