Thanks for spotting this.
this particular error means that you've got odd bytes allocated in ram.
This is not easy to make a decision what to do -- either patch malloc or
linker scripts.
Possible solutions for you now will be:
1. Just define dummy char variable somewhere.
- or -
2. do not use malloc :)
3. patch malloc:
