Package: libgnat-3.15p-1
Version: 3.15p-10
Severity: important
File: gnat-3.15

also involves using g++ (gcc version 3.3.4 (Debian 1:3.3.4-6)).

Try the following:

file cplusplus.cpp contains
#include <iostream>

void except (void) {
  try {
    std::cout << "before" << std::endl;
    throw 42;
    std::cout << "after" << std::endl;
  }
  catch (...) {
    std::cout << "handle" << std::endl;
  }
}

extern "C" void fun (void) { except(); }

file cpp.adb contains
procedure Cpp
is

   procedure Fun;
   pragma Import (C, Fun, "fun");

begin
   Fun;
end Cpp;


Now for compilation do
g++ -c cplusplus.cpp
gnatmake cpp -largs cplusplus.o --LINK=g++

./cpp

which gives 
before

raised PROGRAM_ERROR : unhandled signal

The program immediately crashes when raising an exception within the c++
part of the programm.
