This is happening in a line that was introduced in bug 1652958 so it's a potential regression. Martin can you please have a look?

The change was just atomic_fetch_add_explicit(-1) => atomic_fetch_sub_explicit(1) rename, it didn't change any behavior.
Let's keep eye on that if there's any bigger crash volume here.
