The code is simply broken and produces undefined behavior. Comment All processing in your recursive subroutines and declare a global counter of recursive calls.

I hope that everything will be clear now 😉 Reply Greg says: January 13, 2005 at 10:11 am Correct about spotting some of my assumptions. Thank you, Steve for the note! It's rarely something you can recover from, so your best course of action is just let it crash. Once it crashes you can look at the exception code to decipher what Does it make sense? I added print*, in the recursive subroutine.
I see that when I run the program again, it stopped at the "malloc.c"... Try to set the following combinations of Min and Max Virtual Memory values: [ Case 1 ] Min = 6GB Max = 12GB [ Case 2 ] Min = 8GB Max Thanks iliya. C++ Catch Read Access Violation At any rate, this isn't a matter of catching exceptions, it's a matter of fixing your pointers so that you don't reference them unless they're good.
Also, please attach malloc.c because depending on a version of Visual Studio some differences are possible. 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 bytesThen it continues Top emreka82 Mon, 03/18/2013 - 05:58 Quote:Sergey Kostrov wrote: >>I applied first 3 actions. http://stackoverflow.com/questions/30806174/catch-the-access-violation-reading-location-0x00000000-exception The "Stack Size" problem has seemed reasonable.

This looks like a case where abc->Caller() is returning an uninitialized pointer. It's hard to tell from these code snippits.

How did Adebisi make his hat hanging on his head? http://3swindows.com/access-violation/exception-thrown-read-access-violation-c.html In fact, from the C++ pint of view there's no exception here at all. Finally, [quote=ycinar] the code is really all over the place.. The correct thing to do is to see why Caller() is returning garbage. Yes With Seh Exceptions

Pointers in general are one of the most challenging topics in computer science, which is yet another reason this crash is so commonly seen. -Greg Comments (7) Cancel reply Name You have to do that in your own code, before your application does something so bad that the OS is forced to try to terminate it. It has "MachineX86 (/MACHINE:IX86)" or "not Set" selections. Use separate headers for different classes and separate source files for different classes.
