Created an attachment (id=775)
extract this and run compile.sh to cause the segfault

The dmd compiler segfaults when compiling the attached code.  Extract the archive and run compile.sh.  dmd v2.048 on Ubuntu 10.04 32bit.

Please overlook my messy and error riddled D code as I'm actually in the process of converting a Vala program to D.

I suggest you to slowly reduce the code, until it's just few lines of code.

Okay.  I can reduce it if you need me to.  Or does D have a debugging tool where you can simply run the program under the debugger and it will show you where the segfault came from?

It's OK, I'm able to reproduce it.

TEST CASE
---------
void bug4938()
{
    try
    {
        return 0;
    }
    catch (Undefined4938 ee)
    {
        return 3;
    }
}
-----------

PATCH
statement.c, line 4132.
-----------
int TryCatchStatement::blockExit()
{
    assert(body);
    int result = body->blockExit();

    int catchresult = 0;
    for (size_t i = 0; i < catches->dim; i++)
    {
        Catch *c = (Catch *)catches->data[i];
+        if (c->type == Type::terror)
+            continue;
        catchresult |= c->blockExit();

        /* If we're catching Object, then there is no throwing
         */
+       assert(c->type->toBasetype()->isClassHandle());
        Identifier *id = c->type->toBasetype()->isClassHandle()->ident;
