<pre>This program should cause a length_error immediately but it doesn't. This
behavior is followed by GCC 10 and MetroWerks C++ compilers.
#include <iostream>
#include <string>
using namespace std;
int main(int argc, const char * argv[])
{
string buffer("hi");
try {
std::string mystring(buffer.max_size()+1, 'X');
}
catch(length_error &l) {
cout<<"Caught length_error exception: "<<l.what()<<endl;
}
catch(exception &e) {
cout<<"Caught exception: "<<e.what()<<endl;
}
return 0;
}
What actually happens is the program crashes with EXC_BAD_ACCESS on Mac OS
10.8. Clang 5.1 and Clang 10.0.0.1 have this issue.</pre>
