We have as well faced and came across such issue but its because of compilation of templates again and again. To avoid this we did the below settings, Enable prod mode Enable template caching Set the template compiled directory location – to store the compiled version of template files. (Dont confuse with template directory configuration) … Read more
This happened to me after updating the provisioning profile. It started working after restarting Instruments.
template<class Y> explicit shared_ptr(Y* p); [util.smartptr.shared.const]/6 Throws: bad_alloc, or an implementation-defined exception when a resource other than memory could not be obtained. [util.smartptr.shared.const]/7 Exception safety: If an exception is thrown, delete p is called. So no, no memory leak.
You could have a circular reference in one of your objects. When the garbage collector comes along to deallocate this object, the circular reference means that everything referred to by that reference will never get freed. You can check for circular references with Devel::Cycle and Test::Memory::Cycle. One thing to try (although it might get expensive … Read more
What Is [Cycle Detected] when viewing managed memory? When viewing Heap snapshots inside Visual Studios Diagnostic tools you have: The Object Type Window which shows objects held in memory. When you select a particular Object Type, you can access: Paths to Root – Don’t be fooled by the fact this information is presented in a … Read more
Yes, leaking memory in Rust is as easy as calling the std::mem::forget function. You can also leak memory if you create a cycle of shared references: A cycle between Rc pointers will never be deallocated. For this reason, Weak is used to break cycles. For example, a tree could have strong Rc pointers from parent … Read more
Warning: This answer pertains to C++ only; the rules are quite different in C. Won’t x be leaked? No, absolutely not. It is a myth that goto is some low-level construct that allows you to override C++’s built-in scoping mechanisms. (If anything, it’s longjmp that may be prone to this.) Consider the following mechanics that … Read more
In a Fragment with UI you often save some Views as instance state to speed up access. For example a link to your EditText so you don’t have to findViewById it all the time. The problem is that a View keeps a reference to the Activity context. Now if you retain a View you also … Read more
It causes undefined behaviour. Anything can happen. In practice, a runtime crash is probably what I’d expect.
Generally, failing to close cursors is one of the most common kinds of memory leaks. The garbage collector can’t see the MySQL resources involved in the cursor. MySQL doesn’t know that the Python side was released unless the close() method is called explicitly. Rule of thumb. Open, use and close cursors in as short a … Read more
