Access Violation Writing Location Visual Studio


Let me provide you with some real numbers for Stack Commit and Reserved values used for a Merge Sorting algorithm ( recursive ) to sort very large data sets ( greater Top Steve Lionel (Intel) Sun, 03/17/2013 - 10:14 Use the stack frame dropdown to see where malloc was called from in your source (indirectly). I declared 1000 elements in that table, so I've put something like that: for (int i = 0; i <= 1000; i++) { TAble[i].name = "Some Guy"; TAble[i].age = 4; } And 228 bytes sounds suspiciously like the size of a modest-sized class or object. navigate here

How to bevel only one end of a cylinder? It may be several frames up I see that, but cannot reach malloc.c using stack frame.

scu_sundy 15-Mar-11 1:30am I dont need allocate memory in class 'Thread',m_pool was passed and set to "CThreadPool*" after Thread object was created in CThreadPool::CThreadPool(). 4 solutions Top Rated Most If you're not using MFC, just look up non-blocking thread calls and/or synchronization methods for whatever your framework happens to be. The problem stayed the same with small differences: Unhandled exception at 0x77913560 in 3d.exe: 0xC0000005: Access violation writing location 0x00000000001e0e84. Now that could be the base address of some dll (unlikely) or it could be a memory mapped file or device of some kind (more likely to get a round number

  2. Can you check what is wrong before it crashes? –David Rodríguez - dribeas Feb 11 '14 at 5:04 add a comment| up vote 0 down vote You should check your pointers.
  3. This could lead me to proper ways to use it.
  4. You can check what is going on if you ask the debugger to break on first chance exceptions.
  5. So, as soon as it reaches 173 ( or so ), call a return in order to "unwind" all resursion calls 5.
  6. In Visual Studio check Advanced properties of the Linker and your Target Machine needs to be MachineX64 (/MACHINE:X64), that is for a 64-bit Windows platform.
  7. You can do that in your destructor you mut wait until the thread execution is finished by WaitForSingleObject(hYourThread,INFINITE).Regards.

Is it a good idea at all to employ Singleton pattern here? undo a gzip recursively Electrical Propulsion Thrust Why do shampoo ingredient labels feature the the term "Aqua"? The second line is 74 of write.c, other "call stack locations" are: 3d.exe!for__write_output() + 0x58c bytes 3d.exe!for__put_sf() + 0x129c bytes 3d.exe!for__write_seq_lis_xmit()+ 0x2fbb bytes 3d.exe!for__write_seq_lis() + 0x988 bytes

Then it continues 0xc0000005: Access Violation Reading Location 0xcccccccc. Is it bad practice to use GET method as login username/password for administrators?

The myMap array is local, which is why a pointer-related error being thrown confuses me. –Linky May 22 '11 at 3:45 | show 7 more comments up vote 3 down vote I recently came across Lightning.NET and decided to give it a try as a low-latency history provider for ASP.NET project I'm working on. The goal is as follows: you need to create a simplified and very clean version of your processing ( Do Not worry about results yet! ) and when it Did Not useful source This way you will find the point in your code where it goes wrong and can step the program line by line.

If it were me I would pick a point in the recursive code and set a conditional break in the VS debugger to break (for example) after every 100 hits. Access Violation Writing Location C++ Another possibility is that you accessed an object that has been deleted. Comment All processing in your recursive subroutines and declare a global counter of recursive calls. The proper way of doing this within MFC would be to PostMessage() when you're done and wait for a synchronization signal.

The issue is solved. While debugging they both have things like bad pointer standing in the locals window. Access Violation Writing Location Visual Studio Aug 20, 2012 at 8:50am UTC dorien (14) This is the part that gives the exception: 1

Next time the debugger should break immediately at the moment when the exception is raised. Access Violation Writing Location 0x00000000. The error message is also telling you what the address that you attempted to access is and what type of access you attempted. via->deeper = (Position *)malloc(sizeof(Position)); memset(via->deeper, 0, sizeof(Position)); This way you will ever have reliable values.

Aug 20, 2012 at 10:44am UTC Moschops (7128) If you build with debug symbols included, you'll get more information.

I see that when I run the program again, it stopped at the "malloc.c"... And yet another possibility is that you have reinterpreted (cast) an object to something that it is not and wound up with an address through a bogus calculation. ****** But enough Why are you using rvalue references (&&)? 0xc0000005: Access Violation Writing Location 0x00000000. I'm guessing you are learning C++, and I'm guessing you don't get the nuances of rvalues.

I will apply rest of your action suggestions and see what happens. Try to set the following combinations of Min and Max Virtual Memory values: [ Case 1 ] Min = 6GB Max = 12GB [ Case 2 ] Min = 8GB Max Before deciding to start this topic, I search the forum and other sources.
