[Bug c++/18517] New: throwing not-yet-defined exceptions from templated function kills GCC

["elegant_dice at yahoo dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following code causes GCC to suck up all RAM when 'throw error1;' is
uncommented, and to output the following error when 'throw error2;' is uncommented:

kill_gcc.cpp: In function `void test() [with T = int]':
kill_gcc.cpp:5: internal compiler error: in c_expand_expr, at c-common.c:4341
Please submit a full bug report,
etc etc etc

The code:
-------------------------------
template <typename T>
void test()
{
  // throw error1;  // to suck up all memory
  // throw error2;  // to crash gcc
}

#include <stdexcept>

struct error1 : std::runtime_error
{
  error1() : std::runtime_error("") {}
};

struct error2 {};

int main()
{
  test<int>();
}
