Comment (by olli):

 - 32bit MSVC works
 - 64bit MSVC crashes the app - no info regarding to this issue found in
 the INet
 - compiler using C++ Itanium ABI are problematic because
 __cxa__get_globals() does call malloc()
   store/restore of {{{__cxa_eh_globals::caughtExceptions}}} and
   {{{__cxa_eh_globals::uncaughtExceptions}}} per context we might end up
 with memory leaks (== closing a
   context without cleaning up its list of the active exceptions).

 => maybe the best solution would be a hint in the docu. not to call
 context inside a catch-block
