# All remaining allocations are on addresses which were never freed.

# A leaky allocation will give many different addresses (because it's never freed,
# the address can not be reused).
# * Remove the address (field #4).
# * Count the allocations per every unique source line and alloc type.
# * Show largest counts on top.
