msvc

Visual Studio added code analysis (/analyze) for C/C++ in order to help identify bad code. This is quite a nice feature but when you deal with and old project you may be overwhelmed by the number of warnings.

Most of the problems are generating because the old code is doing some ASSERT at the beginning of the method or function.

I think this is the ASSERT definition used in the code (from afx.h)

#define ASSERT(f)          DEBUG_ONLY((void) ((f) || !::AfxAssertFailedLine(THIS_FILE, __LINE__) || (AfxDebugBreak(), 0)))

Example code:

ASSERT(pBytes != NULL);
*pBytes = 0; // <- warning C6011: Dereferencing NULL pointer 'pBytes'

I'm looking for an easy and safe solution to solve these warnings that does not imply disabling these warnings. Did I mention that there are lots of occurrences in current codebase?
