You can have an arbitrary number of exceptions active in a C++
program at the same time. Where the implementation store the
exception objects in unspecified, but something at least as
powerfull as a stack is need.

Hello!
The question: does the stack of exceptions exist in C++ realizations
conforming to standard?
Consider the following:
class Ex_t {};
class Ex2_t {};
void f() {
try {
throw Ex_t();
}
catch( Ex_t& Ex ) {
try {
throw Ex2_t();
}
catch( Ex2_t& Ex2) {
...
}
throw; // this rethrow the Ex, neither the Ex2 nor another
}
}
One opinion is that it is possible and correct; another says that attempt to
throw another exception in body of catch block must fail with terminate().
What opinion is right?
