The memory leak occurs only if a VCL Dll is loaded the main application without loading any dll or a CBuilder Dll with no VCL has no memory leak. The size of the leak depends on the number of VCL dlls loaded.ДЄlthough it's not a good idea to create threads permanently, we can't prevent any loaded dll's from doing this.

I have still the vague hope that it's only a misinterpretation of us.ДЄ) Plain empty Dll created in Delphi 2009 or CBuilder (VCL) - no additional code entered - a simple empty dllД«) Main application (language and compiler irrelevant) which loads the Dll from a) dynamically and creates / terminates threads inДЇor each thread generated we experience a memory leak.

If you receive a stack full error message this is probably because you have a function recursively calling itself forever, not because the stack space is too limited.Can anybody reproduce the following memory leak in Delphi 2009 / CB 2009 (VCL) ? In Delphi you set this in the linker page of the project options, however, the default generally does it. Windows applications can reserve a large amount of memory for the stack.

See the heap entry in this glossary.Дelphi uses the stack for routine parameters and return values (unless you use the default register calling convention), for local routine variables, for Windows API function calls, and so on. The other two are called global memory and heap. The stack is one of the three memory areas available to an application. Also the variables you declare within a routine (using a var block before the begin statement) are stored on the stack, so that when the routine terminates they'll be automatically removed (before getting back to the calling routine, in LIFO order). When you call a routine, its parameters and return type are placed on the stack (unless you optimize the call, as Delphi does by default). Stack memory is typically used by routines (procedure, function, and method calls). This means that the last memory object you've allocated will be the first to be deleted. The stack allocation is LIFO, Last In First Out. The term Stack indicates a portion of the memory available to a program, which is dynamic but is allocated and deallocated following specific order. Windows allows an application to have up to 2 GigaBytes of address space, most of which can be used by the heap. For the stack see the specific entry in this glossary.Дelphi uses the heap for allocating the memory of each and every object, the text of the strings, for dynamic arrays, and for specific requests of dynamic memory (GetMem). Contrary to the heap, global variables are allocated when the program starts and remain there until it terminates. The other two are the global area (this is where global variables live) and the stack. The heap is one of the three memory areas available to an application. The heap manager takes care of all the details for you, so you simply ask for new memory with GetMem or by calling a constructor to create an object, and Delphi will return you a new memory block (optionally reusing memory blocks already discarded). This means that if you allocate three blocks of memory in sequence, they can be destroyed later on in any order. The heap is the area in which the allocation and deallocation of memory happens in random order. The term Heap indicates a portion of the memory available to a program, also called dynamic memory area. They might also be defined elsewhere in the text, but I've decided to collect them here anyway, to make it easier to find them. This is a short glossary of technical terms used throughout the book.
