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>();
}
