>Description:
GCC crashes when the following (simple) code is compiled:
$ /home2/veksler/gnu2/bin/g++ -O -c t.cpp             t.cpp: In member function `virtual void SubClass::f()':
t.cpp:20: Internal compiler error in remove_eh_handler, at except.c:2696
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.

In the example there are no pre-processor directives, so temp files
are not sent with the report.

----- t.cpp start ----
// Run this with g++ -O -c t.cpp
class Base
{
public:
  virtual void f( );
};

class SubClass : public Base
{
public:
  void f();
};

void SubClass::f()
{
    try {
    } catch(int) { 
    } catch(...) {
    }
}
----- t.cpp end ----
