Hello, I wrote a simple D program to test the immutable attribute and
discovered that by using standard input I could change immutable data, see code
below.
import std.stdio;
void main() {
//Initialize string buf
immutable char[] buf = "hello";
writefln("buf = %s",buf);
//Change value of buf with standard input
stdin.readln(buf);
writefln("buf = %s",buf);
}
Cheers
Robert

Reduced to:
void main()
{
immutable char[] buf = "hello";
void fun(ref immutable(char)[] a) {}
fun(buf);
}
This is a major bug. Please vote. Walter, it would be great if you gave this
the utmost attention.

Seems to compile on all platforms.
Runs fine on Windows.
Segfaults on Linux, doesn't when using 'string buf' instead.

Others marked as duplicates as this is the version that has the most votes,
highest priority and is the only one that has been assigned.

There are several bugs whereby one can overwrite immutable data. See issue
2573.
