Hello,
cc1plus.exe crashes (together with Windows prompt "Program has stopped
working...") while compiling the following code (if it is of any use):
#include
using std::function;
typedef function int_int_f;
int_int_f a = [] (int x)
{
return x + 3;
};
function b = [] (int_int_f f)
{
return [=] (int x)
{
return f(x) * f(x);
};
};
int main()
{ }
Command line:
g++ -std=c++0x -Wall crash.cpp
Compiler produces no warnings or errors.
