>Description:
When compiling the enclosed source with -fno-rtti, the
generated program crashes with SIGSEGV in __cplus_type_matcher with the following backtrace:

  #0  0x80487c0 in _IO_stdin_used ()
  #1  0x40039034 in __cplus_type_matcher ()
     from /usr/lib/libstdc++-libc6.1-2.so.3
  #2  0x40038453 in __eh_rtime_match () from /usr/lib/libstdc++-libc6.1-2.so.3
  #3  0x804871d in g (i=0) at gcc-throw-bug.cpp:57
  #4  0x8048758 in main () at gcc-throw-bug.cpp:63

I believe if the compiler is unable to generate correct code, it should give an compiler error.
>How-To-Repeat:
Compile the source with -g -fno-rtti and run the resulting
program.
