#include <iostream>
#include <string>

int main(void)
{
    string test("david");
    string bad;

    bad.reserve(500);
    cout << "bad capacity: " << bad.capacity() << endl;
    
    cout << "test capacity before: " << test.capacity() << endl;
    test.reserve(500);
    cout << "test capacity after: " << test.capacity() << endl;

    return 0;
}
// END OF SOURCE

this code prints
bad capacity: 0
test capacity before: 16
test capacity after: 16

shouldn't the "test capacity after" be 500?

State-Changed-From-To: open->closed
State-Changed-By: paolo
State-Changed-When: Sat Mar  1 16:37:05 2003
State-Changed-Why:
    According to the standard, should be >= 500.
    Indeed, the output for the current release of gcc
    (i.e., 3.2.2) is 611.
    I suggest updating your development tools: the 2.95.x
    branch is *very* old and not maintained anymore.
    Thanks for your report,
    Paolo.
