            Bug ID: 64165
           Summary: __builtin_frame_address causes segmentation fault in
                    __static_initialization_and_destruction_0
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: angeldevil_007 at mail dot ru

Simple example working for me:

#include <memory>
#include <cstdio>


struct test_t {
    test_t() {
        std::printf("%p",
                __builtin_frame_address(0) ?
                    (__builtin_frame_address(1) ?
                        (__builtin_frame_address(2) ?
                            (__builtin_frame_address(3) ?
                                __builtin_frame_address(4)
                                : nullptr)
                            : nullptr)
                        : nullptr)
                    : nullptr);
    }
};


test_t obj;

int main(int, char **) {
    return 0;
}

Compile:
g++ -std=c++0x main.C -o test -fno-omit-frame-pointer
g++-4.9 -std=c++11 main.C -o test -fno-omit-frame-pointer

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---

#3  0x000000000040061d in __libc_csu_init ()
#4  0x00007ffff7a3c700 in __libc_start_main (main=0x4004f4 <main>, argc=1,
ubp_av=0x7fffffffeb68, init=0x4005c0 <__libc_csu_init>, fini=<optimized out>,
rtld_fini=<optimized out>, stack_end=0x7fffffffeb58) at libc-start.c:185


__libc_csu_init does not have a frame pointer so it crashes.  NOT unexpected.
