Because the heap tends to fragment over time, some GC policies might be forced to run a global garbage collection and defragmentation (compaction) to recover sufficient contiguous memory to allocate a large array. By removing the requirement for large arrays to be allocated in contiguous memory, t...
Objects allocated on the stack are available only inside of a stack frame (execution of a method), while objects allocated on the heap can be accessed from anywhere. Q: Which objects are allocated on the stack and which objects are allocated on the heap? Note: you should never say "refere...
The heap segment provides more stable storage of data for a program; memory allocated in the heap remains in existence for the duration of a program. Therefore, global variables (storage class external), and static variables are allocated on the heap. The memory allocated in the heap area, if...
" For example, if you have a list of read-only items that is loaded at application initialization time, this list does not need to be a linear-linked list. It can very well be a dynamically allocated array. A dynamically allocated array would reduce heap blocks in memory, reduce ...
Since you do not have a pointer to the freestore allocated object, it causes a memory leak. Note that if the destructor of Foo has some code which causes side effects then it is not merely memory leak but undefined behavior. Share Improve this answer Follow answered Feb 24, 2013 at 7...

I was recently reading about stack & heap corruption in C & C++. The author of the website demonstrates stack corruption using below example. #include<stdio.h>intmain(void){intb =10;inta[3]; a[0] =1; a[1] =2; a[2] =3;printf(" b = %d \n",b); ...
The results of the analysis can be used by parallelizing compilers to determine when two heap-allocated objects are guaranteed to be disjoint, and thus can be used to improve array dependence and interference analysis. The method has been implemented as a context-sensitive interprocedural analysis ...
