descriptionThe build log contains the term
warning: attempt to free a non-heap object
This means gcc detected 'free' called for a object non on the heap (i.e. something not supposed to be free'd).
This can be a false-positive if it is code that is never actually called. Otherwise it might cause to the program getting aborted with an error message or even a silent corruption of the program's memory management.
