import std.stdio;

void main()
{
    try {
        byte[] big_buf = new byte[4294967295];
        writeln("Allocated");
    }
    catch(Exception) {
        writeln("never displayed");
    }
}


The string "never displayed" is never displayed and the client crushes with
object.Error: Access Violation.

Same if instead of (2^32 -1) you put -1.

It is to be expected that catch(Exception) will not catch an Error, because
Exception is not a super class of Error.

However, the code snippet should throw OutOfMemoryError. There should not be an
access violation.
