Hello,

in file socket.d i get an error message:
gdc -c socket.d
socket.d:
In function `add':
socket.d:0: interner Compiler-Fehler: Speicherzugriffsfehler
Please submit a full bug report,
with preprocessed source if appropriate.
See
<URL:http://gcc.gnu.org/bugs.html> for instructions.

the function add start
in line  780 .

Here is a code snip

typedef int socket_t = -1;
const
socket_t INVALID_SOCKET = socket_t.init;
void add(socket_t s)
//      /*
in
        {
                version(Win32)
                {
assert(count < max); //added too many sockets; specify a higher max in the
constructor
                }
        }
        body
//        */
        {
version(Win32)
                {
                        uint c = count;
first[c] = s;
                        count = c + 1;
                }
else version(linux)
                {
//bts(cast(uint*)&first[fdelt(s)], cast(uint)s % nfdbits);
                }
else
                {
                        static assert(0);
}
}


You can put this in a file and try to compile there appear the same error
message.
I believe the problem is the "in" and "body" statements.

I found the minimal code of this problem.

void bug()
in {
    version (Win32) { // it's safe when it is 'linux' (on Linux)
    }
}
body {
}

And I found another fatal bug:

void bug() {
    char[][int] a;
    int[] i = a.keys;
}

> gdc -c bug_assoc_key.d
bug_assoc_key.d: In function `bug':
bug_assoc_key.d:0: internal compiler error: in emit_move_insn, at expr.c:3165
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

And not fatal bug:

void bug() {
    typedef double D;
    D d = cast(D)0.0;
}

Please submit a full bug report,

See <URL:http://gcc.gnu.org/bugs.html> for instructions.

And I cannot judge whether it's a bug or not:

void bug() {
    int d = 1;
    d /= 1.0;
}

I'm sorry I post continuously.

I found another fatal bug:

class Base {
        void bug() {}
}
class Derived : Base {
        void bug() { super.bug(); }    // call Derived::bug!
}
int main() {
        Base b = new Derived();
        b.bug();
        return 0;
}

It can be compiled and linked, but it fail with segmentation fault.
Because super.bug() call Derived::bug() recursively.
