This indeed would give me the behaviour I want as also redefining throw with 
a macro (as Peter suggested).

Setting BOOST_NO_EXCEPTIONS however (which changes the semantics of the 
program) just for catching my out-of-bounds-error is a little drastic.
It does indeed abort on the out-of-bouds error but the rest of my code that 
might rely on exceptions also changes and thus is not an optimal solution.

Using the macro as Peter suggested also has this global effect (changes the 
behaviour of _all_ exceptions) and I always get uncomfortable with macros.

Therefor my suggestion to just put an assert() just before the throw point.
Both in debug mode and release mode it exactly does what I want, provide me a 
stack-trace in debug mode and throw an exception in release mode while not 
affecting any other part of the program.
