问题
When I compile on VS 2008 in deubg mode everything works fine. When I compile the same thing in release mode not everything works. As far as I can tell the include directories are the same and there are no additional preprocessor symbols.
Any help?

The line of code it eventually points to is:
std::vector<CodeInfo, AllocatorWithCleanup<CodeInfo> > m_codeToValue;
Edit: More info:
I get this error exactly when my preprocessor contains NDEBUG instead of _DEBUG. If I change my release config to have _DEBUG isntead it compiles. Why?
回答1:
It's a bug in the Visual C++ compiler. See http://old.nabble.com/-jira--Created:-%28QPID-1458%29-C%2B%2B-common-compile-error-in-VC9-Release-mode-td20469700.html.
You can work around it by disabling checked iterators:
#define _SECURE_SCL 0
But be warned: if you link against a third-party library that was compiled with _SECURE_SCL enabled, like e.g. boost, memory corruption can (and will) occur.

Coming back to C++ after many years, I encountered a similar error. Turned out it had nothing to do with this bug and everything to do with the fact that I hadn't updated my Release configuration to the same settings as used in the Debug configuration! So for the other noobs out there -- remember to make sure that you have the same Character Sets, CLR Support, Include Directories, Additional Dependencies, and so forth in all your configurations.
