Most likely, it's because the optimizer did a number on your code and the debugger can't read it anymore. with no success. Refer to the very start of its definition: Code: char* getWord(FILE *file) anyway, arrays cannot be returned from functions. How do i even begin to investigate this?

Visual Studio C++ Unable To Read Memory

Is this a single .exe project, or are you using DLL's (your own or third party)? Thanks in advance. Now what i suspect is that these issues could be because of stack & heap corruptions but i commited and reserved the stack/heap sizes respectively but no success. If the user doesn't supply any arguments then you are accessing an argument that doesn't exist.

Go to Debug -> Exceptions and under Win32 Exceptions check the box in the "thrown" column for "Access Violation." Then once the debugger breaks, you can hover over variables with your But when i executed the new project in debug mode the applicaiton crashes. Solution 2 Accept Solution Reject Solution hi,check that when you are executing this code, are you passing a command line argument ? Source Whether the variable value shown is correct at any given instruction depends on how the underlying register is being used at that point.

If you do this, you should not have to ignore any libraries.

getWord either returns a pointer to the first character of a null terminated string, or it returns a null pointer. If you have a problem specific to Release build, then it's a hint that your code has a dodgy #ifdef in it, or you invoked UB that just happens to work Optional Password I have read and agree to the Terms of Service and Privacy Policy Please subscribe me to the CodeProject newsletters Submit your solution! Error Reading Characters Of String We will contact you if we require any additional information.

However, that's not terribly helpful if you actually have a problem in Release mode you can't find. I'm passing in a value from a char array, and it looks like there is a value there, but once it gets passed to a function the "unable to read memory" I have attempted to make a simple Linked List which compiles, but crashed with an error when I try to run it: https://gist.github.com/anonymous/b690401f5083711cc1b3 (I'm not totally sure on how to format have a peek here This is a much simpler version of the issue without all of the variable names that would clutter and make the problem unclear.

In the meantime, you can work around the problem by changing the underlying type of your enum to be something other than "bool". POD means "plain old data", basic types and structs without any methods ( just like in C). Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool. I fixed the wording. –Zac Howland Jan 11 '11 at 12:55 If its class A then even with NULL pointer it will be not crashed.
