  That was a relatively common problem in C and C++ years ago, but nowadays
especially C++ compilers have got much better at debugging such things. For
example Visual C++, when compiling in debug mode, will add bounds checks to
all STL code and IIRC raw array accesses (although there are limits to the
latter, as it's quite difficult to check bounds when pointer arithmetic is
being performed). gcc has a precompiler constant which, when defined, turns
on similar checks to all STL code. Then you can use valgrind to catch the
rest.

  The only situation nowadays where you might end up having such heisenbugs
in C++ which are not caught by the compiler even in debug mode is if you
use dirty raw pointer arithmetic hacks, which is something you seldom really
have to do in clean good-quality code, not even if you aim for maximum
efficiency.
