            Bug ID: 60516
           Summary: cc1plus crashes compiling a method with a huge struct
                    as argument
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: zaskar_84 at yahoo dot com.ar

cc1plus crashes when trying to compile a class method that receives a very big
argument (a 65kb struct) in Windows (reproducible with mingw32, no problems on
linux versions). I know that we are not supposed to make so big static
variables, but the compiler should compile and let the resulting program crash
or complaint about that instead of crashing itself. Here's the minimal code
that generates the error:

    struct huge {
        char c[256][256]; 
    };
    class Bar {
        void foo(huge x);
    };
    void Bar::foo (huge x) {
    }

I've noted that there's no problem if the method is implemented inline.

And here are versions and compiler output

Tested on win7 ultimate 64bits, g++ was mannually installed, just by
decompressing the following packages from mingw32:
binutils-2.24-1-mingw32-bin.tar.xz expat-2.1.0-1-mingw32-dll.tar
gcc-c++-4.8.1-4-mingw32-bin.tar gcc-c++-4.8.1-4-mingw32-dll.tar
gcc-core-4.8.1-4-mingw32-bin.tar gcc-core-4.8.1-4-mingw32-dll.tar
gdb-7.6.1-1-mingw32-bin.tar gmp-5.1.2-1-mingw32-dll.tar
libiconv-1.14-3-mingw32-dll.tar mingwrt-4.0.3-1-mingw32-dev.tar
mingwrt-4.0.3-1-mingw32-dll.tar mpc-1.0.1-2-mingw32-dll.tar
mpfr-3.1.2-2-mingw32-dll.tar w32api-4.0.3-1-mingw32-dev.tar

The same problem was reproduce by someone else with 4.8.2, see
