OpenIndiana Distribution

I'm having some problems with C++ and -m64, where it works with -m32. I'm running OI151a with GCC 4.6.2 from SFE. The exception is caught with -m32 (as expected), but with -m64 it is not caught and terminate is called. Simple test case below:

mkdir test2
cd test2
cat > test.cc <<EOF
#include <memory>
#include <iostream>
#include <stdexcept>

using namespace std;

int main() {
try {
throw invalid_argument("Hello world");
} catch (exception& e) {
cerr << "Caught exception\n";
}
return 0;
}
EOF

g++ -m32 test.cc; ./a.out

1. Caught exception

g++ -m64 test.cc; ./a.out

1. terminate called after throwing an instance of 'std::invalid_argument'
2. Abort (core dumped)
