The instruction at 0x00427289 referenced memory at 0x7ffdf000. The memory could not be read.

My Application crashes :(( by displaying the message, "The instruction at 0x00427289 referenced memory at 0x7ffdf000. The memory could not be read. Click OK to terminate the program". The Application works fine with debug build but fails with release build. If anyone have any idea with this please let me know. Thanks :rose:
Thanks a lot

Why does program work in debug mode, but fail in release mode? A: First of all, there is no such thing as 'debug mode' or 'release mode'. The VC++ IDE offers the possibility to define configurations which include a set of project settings (like compiler / linker options, output directories etc.) When a project is created using AppWizard, you get two default configurations: "Win32 Debug" and "Win32 Release". These are just convenient starter configurations with several preset options which are suitable for typical debug builds or release builds respectively, but you are by no means restricted to those settings. Actually, you can modify those configurations, delete them, or create new ones. Now let's see what the two default configurations typically include and what distinguishes them: Win32 Debug: Subdirectory 'Debug' used for temporary and output files Preprocessor symbol _DEBUG defined Debug version of the runtime libraries is used All compiler optimizations turned off Generate debug info Win32 Release: Subdirectory 'Release' used for temporary and output files Preprocessor symbol NDEBUG defined Release version of the runtime libraries is used Various compiler optimizations turned on Generate no debug info There are a few other differences, but these are the most important ones. Now, what's the first implication of all this? That, as opposed to a common misunderstanding, you can debug a release build. Just go to 'Project -> Settings', choose the Win32 Release configuration, tab 'C/C++', 'General' and set 'Debug Info' to 'Program Database'. Then go to the tab 'Linker', and turn on 'Generate Debug Info'. If you rebuild your project now, you will be able to run it in the debugger. Regardless of whether your program crashes or just doesn't behave as expected, running it in the debugger will show you why. Note however, that due to optimizations turned on in the release build, the instruction pointer will sometimes be off by a few code lines, or even skip lines altogether (as the optimizer didn't generate code for them). This shouldn't be a concern, if it is, turn off optimizations. When debugging your release build this way, you will probably discover that at a certain point during execution, a variable has a different value in the release and in the debug build, causing the differing behaviour. And if you go back and see where the value of that variable is set, you will most probably find out that it isn't: You simply forgot to initialize that variable. The reason why the debug bu
