A call to Debug.info() with no arguments throws an error in the SWF10 runtime only: ERROR @debugger/LzDebug.lzs≈577: ArgumentError: Error #1063: Argument count mismatch on LzDebugService/warnInternal(). Expected 2, got 1.
It's caused when the function is applied within LzDebug#warnInternal:
return this.warnInternal.apply(this, [LzInfo].concat(args));
Might be better to show a warning instead.
