--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
Unfortunately, the simple patch in the Description doesn't work for char
literals. I.e., this
atomic_char a;
atomic_init (a, 'x');
doesn't compile because __typeof__ ('x') is int and calling __atomic_store with
pointers to types of mismatching size produces:
error: size mismatch in argument 2 of ‘__atomic_store’
atomic_init (a, 'x');
^
This is likely why Clang implements atomic_init in terms of its
__c11_atomic_init intrinsic.
Assigning to self to come up with a better patch.
