Description

// src/buffer.rs:657
    /// Ensures that this buffer has at least `capacity` slots in this buffer. This will
    /// also ensure the new capacity will be a multiple of 64 bytes.
    ///
    /// Returns the new capacity for this buffer.
    pub fn reserve(&mut self, capacity: usize) -> Result<usize> {
        if capacity > self.capacity 

Unknown macro: {             let new_capacity = bit_util}

;
            self.data = new_data as *mut u8;
            self.capacity = new_capacity;
        }
        Ok(self.capacity)
    }

 
Above code is not checking if new_data is null, which is causing segfault on following memcpy when reallocate failed.
