对于 MSVC 默认是 1MB，称为 reserved size of stack allocation in virtual memory，可用 cl /F 选项、link 或 editbin /STACK 选项设置。多线程程序会给每个线程分配各自的栈空间 [3b]。相比于堆，1MB 的栈是一个拮据的空间。所以使用栈中的局部对象时，要评估它是否是大 size 对象，以及
1. Small heap memory blocks that are leaked (allocated but never freed) over time 2. Mixing long lived small allocations with short lived long allocations Both of these reasons can prevent the NT heap manager from using free memory efficiently since they are spread as small fragments that canno...
Why is stack (in context of stack and heap) considered LIFO (last in first out)? The last time i checked, the program can access random memory inside the stack and manipulate it, without need to pull the predecessors memory cells Jan...
The “managed heap” is a section of memory that is automatically managed by the memory manager of a Project’s scripting runtime (Mono or IL2CPP). All objects created in managed code must be allocated on the managed heap(2) (Note: Strictly speaking, all non-null reference-typed objects ...

The heap is reserved for the memory allocation needs of the program. It is an area apart from the program code and the stack. Typical C programs use the functions malloc and free to allocate and deallocate heap memory. The Debug version of MFC provides modified versions of the C++ built-...

HWASAN:HardWare-assistedAddressSanitizer, a tool similar to AddressSanitizer, but based on partial hardware assistance and consumes much less memory. 这里所谓的 "partial hardware assistance" 就是指 AArch64 的TBI(Top Byte Ignore) 特性。 TBI (Top Byte Ignore) feature of AArch64: bits [63:56] ar...
You cannot mix the two and have to use corresponding delete too (for single or for array). You make the error of creating one object but assuming that you have an array. Automatic variables, variables declared within a (function) scope, have memory allocated from stack on call of the ...
