Description

Hi,

Just pulled the latest mruby code, and found that some of my fuzzing test cases now crash. Bisected it to commit 227daa881137d5251e03eea0883b9b574a1f064e. Reverting this change no longer causes a crash.

The minimised file causing the crash is:

f ()

Also affects mruby-engine.

Cheers,

Hugh
