Depending on what you mean by the heap state.
There is an experimental __sanitizer_print_memory_profile (only in asan,
not in standalone lsan)
which will print a simple heap profile. Not much else.
// Prints stack traces for all live heap allocations ordered by total
// allocation size until `top_percent` of total live heap is shown.
// `top_percent` should be between 1 and 100.
// At most `max_number_of_contexts` contexts (stack traces) is printed.
// Experimental feature currently available only with asan on
Linux/x86_64.
void __sanitizer_print_memory_profile(size_t top_percent,
size_t max_number_of_contexts);
