Adresses pr #165 and issue #164 by @colesbury:
...
On Mac OS, the thread-local _mi_default_heap may get reset before
_mi_thread_done is called, leaking the default heap on non-main threads.
Now the current default heap is also stored in mi_pthread_key (or mi_fls_key
on Windows). The _mi_thread_done function is called with this value.

Use checked unsigned multiplication extension of GCC/Clang
...
Most processors have carry flags which they set on addition overflow, so
it is a good idea to access them whenever possible. Most of them also
have widening multiply instructions that can be used to detect overflow
of the non-widening version. Both GCC and Clang offer a way to detect an
overflow for security critical applications.
