Hi,
   Apologies if this is a duplicate. My bugzilla search did not find it.
This is also my first attempt at D programming. An unresolved forward reference
causes a segfault on cygwin. See following code. If the forward reference is
replaced by an empty definition everything is fine.

prompt>gdc --version
gdc (GCC) 3.4.4 (cygming special, gdc 0.12, using dmd 0.125)

As far as I'm aware this is the latest version of gdc available for cygwin.
This is probably the route of the problem.

<code file="foo.d">
class forwardRef;

interface foo {
public:
   abstract void bar(in forwardRef task);

};
</code>

>gdc -c foo.d -o foo.o
foo.d:0: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.

Note: the same problem occurs if -mno-cygwin is used.

Regards,
       Bruce.
