I believe the patch just applied (imported from gcc svn, work by Jason
Merrill) fixes this :
\network\x86\ace> Reactor_Exceptions_Test
(78512150|78577686) Starting Reactor_Exceptions_Test test at Tue Aug 18
2009 21:43:16.859000
Starting tracing
Activity occurred on handle 7!
got buf = Hello
(78512150|91619350) throw exception
(91619350) catch exception
(91619350) exception return

(78512150|78577686) Ending Reactor_Exceptions_Test test t Tue Aug 18

\network\x86\ace>
Also the test you privately sent me is fixed :
\network\x86> static
cFoo constructor
cBar constructor
Foo pointer 16020630 Bar pointer 16020630
I am cBar.
cBar destructor
cFoo destructor
\network\x86> dll

cBar constructor
Foo pointer 180206b0 Bar pointer 180206b0
I am cBar.
