These are very simple questions, but I just want to make sure a few of my assumptions are correct:
1. The default FPC heap manager uses one heap per thread, right? I am basing this assumption off of things I have read in various threads on this and other mailing lists since around 2.2.x-ish. Looking at heap.inc I see that the "freelists" variable is a threadvar, which indicates to me that each thread has its own heap. 2. When a thread is started via, for example, BeginThread (http://www.freepascal.org/docs-html/rtl/system/beginthread.html) this heap, as well as all other threadvars in my code and the rtl code, is setup and initialized automatically, correct? 3. When this thread exits (in the example of using BeginThread, when the TThreadFunc function passed in to BeginThread terminates) the heap for that thread, in addition to the other threadvars, are automatically disposed, correct? The reason I ask is that I have a program (which executes a lot of worker threads via BeginThread) which is experiencing increasing memory usage. heaptrc does not indicate that there are any leaks, but it's a fairly complex program (we have some units where we're getting memory from libc directly, don't ask) so I'm not even supposing at this point that the increasing memory belongs to the FPC heaps at all, but I'm just trying to make sure I understand everything that's going on before I go making assumptions about where the memory allocation is coming from.
