Attempt to free plot data entries in each call to create_plot_info()
In profile.c:create_plot_info(), store the last address in which
memory was allocated for the plot data entries in the static
variable "last_pi_entry". If "last_pi_entry" isn't a NULL
pointer in each call to create_plot_info(), free memory at that
address.
