            Bug ID: 59255
           Summary: Segmentation fault with std::function and
                    -fprofile-use
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: critical
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: stepik-777 at mail dot ru

Consider the following simple program:
#include <functional>

int main(int argc, char *argv[])
{
    std::function<int ()> f = []{ return 0; };
    return 0;
}

I'm compiling it with these commands:
g++ -std=c++11 -fprofile-generate -c test.cpp -o test.o
g++ -std=c++11 -fprofile-generate -o test test.o
./test # execute to generate profiling data
g++ -std=c++11 -fprofile-use -c test.cpp -o test.o
#g++ -std=c++11 -fprofile-use -o test test.o

This causes segfault when compiling with -fprofile-use:
test.cpp: In destructor 'std::_Function_base::~_Function_base()':
test.cpp:7:1: internal compiler error: Segmentation fault
 }
 ^

Tested with these two gcc versions:
g++ (Ubuntu/Linaro 4.8.1-10ubuntu8) 4.8.1
g++.exe (rev0, Built by MinGW-W64 project) 4.8.2
