C++ - detect out-of-range access

问题:

I would like to analyse my C++ code to find bad access in vectors and arrays (out of range access), is there a tool for that ?

thanks in advance

回答1:

You can compile with _GLIBCXX_DEBUG and _GLIBXX_DEBUG_PEDANTIC defined if your are using gcc. This will enable glibc assertions to be raised if out of bounds access is requested.

Testing with valgrind::memcheck will also reveal bad memory reads

回答2:

Yes: Valgrind.

And many others: http://en.wikipedia.org/wiki/Memory_debugger.

Note also that most implementations of e.g. std::vector have a debug mode where they will do run-time bounds checking.

回答3:

There are some paid tools, which does static analysis:

klockwork

coverity

IBM Rational Purify does dynamic analysis.

回答4:

create a class on you arrays and create some controlling functions in that class with operators and .... then use this class .
