[Bug pending/37879] New: g++: internal compiler error: Segmentation fault

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org>]

NOTE: Defaulting component because reported component no longer exists
    ICE: Segmentation fault when compiling with an incorrect used
    __attribute__((noreturn));

How-To-Repeat:
    source code (preprocessed file looks the same):

    inline unsigned f( unsigned i ) { return i; }
    unsigned i = 23;
    static inline void g( unsigned ) __attribute__((noreturn));
    static inline void g( unsigned j ) { if( j ) asm ("hlt"); }
    void main_func() asm("main_func") __attribute__((noreturn));
    void main_func()
    {
        unsigned j;
        g( f( j = i++ ) );
        asm("hlt");
    }

    compile with:    
    g++ -save-temps -m32 -MD -Os -ffunction-sections -fstrict-aliasing

Fix:
