sample program runtime error

C++ coding using Panda3D
1

The following sample c++ program on compilation gives a run time error.After debugging it says there’s a buffer overrun and points to a line in " gc_report.c " . Compiler - VS 2010. How can i get rid of it ?

#include "pandaFramework.h"

Please put your code between

 and

tags when posting on the forums, that makes it more readable.

As for your issue, please make sure you’re using the latest development build of the SDK if you’re using MSVC 2010 and that you’re compiling in Release mode.

Sorry! I’ve edited the code and put it between code tags.
I have the latest SDK and I am compiling it in release mode.Other examples work fine except this one.

By “latest SDK”, which exact version do you mean?

Also, make sure you’re not making a unicode build.

Panda3d version - 1.8.1(Latest stable)
and I am using Multi-byte character set.
