 I can reproduce this only with 3.3 (20030401). Redux is:
 
 ---------------------------------------------
 class __attribute__((dllimport)) Foo
 {
    public:
         virtual void dummy_foo_func(void)
         {}
 };
 
 class Bar : public Foo
 {
     public:
         ~Bar();
         void dummy_bar_func();
 };
 
 Bar::~Bar()
 {}
 
 void Bar::dummy_bar_func()
 {}
 ---------------------------------------------
 pr7910.cpp:20: internal compiler error: Segmentation fault
 Please submit a full bug report,
 
 Notice that Bar's destructor and the other dummy function _must_ be defined
 out of the class definition for the ICE to happen. 2.95, 3.2 and 3.2.2
 compile the code correctly. I can't test with 3.4 (mainline broken for
 cygwin).
 
 3.3 regression only.
