 Hi,

 First a disclaimer: I _think_ that this used to work before, but no longer
 does.  I tend to think that it used to work, because the test suite of
 Bison was all green a few months back, but today there are fails because
 of the following failure.  It might have something to do with the libgcc
 changes, but I could not find an "obsolete" machine on which I could check
 this.

 And also, I understand that these compilers are old.

 On the following test case:

 {{{
 #include <iostream>
 #include <stdexcept>

 void foo()
 {
   try
     {
       throw std::runtime_error("foo");
     }
   catch (...)
     {
       std::cerr << "Inner caught" << std::endl;
       throw;
     }
 }

 int main()
 {
   try
     {
       foo();
     }
   catch (...)
     {
       std::cerr << "Outer caught unknown" << std::endl;
     }
 }
 }}}

 neither g++-mp-4.3 nor 4.4 produce a functioning executable:

 {{{
 $ g++-mp-4.3 exc.cc && ./a.out
 Inner caught
 zsh: abort      ./a.out
 $ g++-mp-4.4 exc.cc && ./a.out
 Inner caught
 zsh: abort      ./a.out
 $ g++-mp-4.5 exc.cc && ./a.out
 Inner caught
 Outer caught unknown
 $ g++-mp-4.6 exc.cc && ./a.out
 Inner caught
 Outer caught unknown
 $ g++-mp-4.7 exc.cc && ./a.out
 Inner caught
 Outer caught unknown
 $ g++-mp-4.8 exc.cc && ./a.out
 Inner caught
 Outer caught unknown
 $ g++-mp-4.9 exc.cc && ./a.out
 Inner caught
 Outer caught unknown
 $  exc.cc && ./a.out
 }}}

 I'm using libgcc-devel, but trying with libgcc didn't change.
