--------------------------------------------------
Key: STDCXX-1062
URL: https://issues.apache.org/jira/browse/STDCXX-1062
Project: C++ Standard Library
Issue Type: Bug
Components: 23. Containers
Affects Versions: 4.2.1, 4.2.x, 4.3.x
Environment: Solaris 10 and 11
RedHat Linux, OpenSuSE Linux
Defect is independent of platform and/or compiler
Reporter: Stefan Teleman
Fix For: 4.2.2, 4.2.x, 4.3.x, 5.0.0
The std::vector<bool>::at() specialization throws the wrong exception:

#include <iostream>
#include <vector>
#include <stdexcept>
static const size_t maxlen = 10;
int main()
{
size_t i;
bool b;
int r;
int ret = 0;
int x = 0;
std::vector<int> vi(maxlen, 1);
std::vector<bool> vb(maxlen, false);
try
{
r = vi.at (12);
}
catch (std::out_of_range& e)
{
std::cerr << "std::vector<int>::at(12): OK" << std::endl;
++x;
}
catch (std::exception& e)
{
std::cerr << "std::vector<int>::at(12): wrong exception: "
<< e.what() << std::endl;
++ret;
++x;
}
catch ( ... )
{
std::cerr << "std::vector<int::>at(12): wrong exception!"
<< std::endl;
++ret;
++x;
}
try
{
b = vb.at(12);
}
catch (std::out_of_range& e)
{
std::cerr << "std::vector<bool>::at(12): OK" << std::endl;
++x;
}
catch (std::exception& e)
{
std::cerr << "std::vector<bool>::at(12): wrong exception: "
<< e.what() << std::endl;
++ret;
++x;
}
catch ( ... )
{
std::cerr << "std::vector<boolt>::at(12): wrong exception!"
<< std::endl;
++ret;
++x;
}
if (x == 0)
{
std::cerr << "no exception was thrown" << std::endl;
++ret;
}
return ret;
}
