gcc (GCCSDK GCC 4.7.4 Release 1 Development) 4.7.4 20140529 (prerelease)
[gcc-4_7-branch revision 211052]
SharedUnixLibrary 1.12
VirtualRPC-Adjust RISCOS 4.39, ARM 710

With this program:

#include <iostream>
int main(void) {
try {
throw 5;
}
catch (int i) {
std::cout << "caught " << i << std::endl;
}
return 0;
}

I get:

*g++ exceptions.cc
*a/out
terminate called after throwing an instance of 'int'
terminate called recursively

Fatal signal received: Aborted

Stack backtrace:

With gcc 4.1.2 I get, as expected:

*a/out
caught 5
