I just confirmed this with Jon online, this bug is not in CVS (0.30)
anymore. Here's the program we used to test:
using System;
using System.Runtime.InteropServices;
using System.Text;
class Test {
[DllImport ("libc")]
static extern IntPtr strncpy (
StringBuilder dest, string src, uint len);
static void Main ()
{
string src = "test";
uint len = (uint) src.Length;
StringBuilder dest = new StringBuilder (src.Length);
for (int i = 0; i < 10; i++) {
strncpy (dest, src, len);
Console.WriteLine (dest.ToString ());
}
}
}
The output is 10x "test".
I don't have time to check whether or not we have this in the test suite
somewhere now, but if we don't, we ought to.
Duncan.
