            Bug ID: 61048
           Summary: compiling with -fsanitize=address crashes GCC if
                    pointers are used
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fabian@ritter-vogt.de

test.cpp:
include <iostream>
int main()
{
        int *i = reinterpret_cast<int*>(0xC1000000);
        std::cout << *i << std::endl;
}

Compile with:
arm-none-eabi-g++ test.cpp -c -o test.o -fsanitize=address -flto
Link with:
arm-none-eabi-g++ test.o -o test -Wl,-flto

arm-none-eabi-g++ -v:

It compiles fine if I remove "-flto" (disregarding undefined references)
