Running into memory allocator assert (prev_free field can not be null)


I am running into an tlsf_assert in remote_free_block where “prev_free field can not be null”. What does this mean and how can this condition be triggered? If the block is the head of the list, is it not expected that the prev_free points to NULL?

I am running v8.3.3. Any pointers or help would be much appreciated
