libfuzzer questions
First off, thanks -- this is a pretty great library and it feels like I'm
learning a lot. I'm getting some more experience with libfuzzer and
finding that I have a couple of questions:
- How does libfuzzer decide to write a new test file? What distinguishes
this one from all the other cases for which new test inputs were not

RFC: Sanitizer-based Heap Profiler
...tack alloc context id is found, a new entry is
created. If this causes an eviction, the evicted entry is dumped
immediately (by default to stderr, otherwise to a specified report file).
Later post processing can merge dumped entries with the same stack alloc
context id.
Initialization
For ASAN, an __asan_init function initializes the memory allocation
tracking support, and the ASAN instrumentation pass in LLVM creates a
global constructor to invoke it. The heap profiler prototype adds a new
__heapprof_init function, which performs heap profile specific
initialization, and the heap profile instrumen...
