Crash when fRefCnt.fetch_add

[l1 shu]

Hi team, I got an error:

the final call is `__c11_atomic_fetch_add`, I don't know where the problem is, can someone help me point out my question? Thanks

More information is:

When I return an sk_sp<SkShader>  object, It enters the skia internal logic

1. return sk_sp<SkShader>
2.  sk_sp<T>& operator=(sk_sp<T>&& that) {
         this->reset(that.release());
         return *this;
      }

3. void reset(T* ptr = nullptr) {
         T* oldPtr = fPtr;
         fPtr = ptr;
         SkSafeUnref(oldPtr);
     }

4. template <typename T> static inline void SkSafeUnref(T* obj) {
         if (obj) {
             obj->unref();
         }
     }

5. void unref() const {
         if (1 == fRefCnt.fetch_add(-1, std::memory_order_acq_rel)) {
             this->internal_dispose();
         }
     }

6. Unfortunately crash...

Ignore the discussion, I figure it out
