    Try with current version. My be it's solved in 2.4.8 #987
    (see changelog). I got the signal 11 too and detected a
    memory allocation problem, which was solved by erik

    I tried it with MINGW sdcc version 2.4.8 #1001 on Windows
    2000 and it doesn't crash.

    This now will compile after making the array
    const char s[4] = { 1, 2, 3, 4 };
    global (complex-typed locals seem still to be broken).
    It crashed because of a bug in genarith.c:genAdd (index
    out-of-bounds), fixed in SDCC 2.5.1 #1053.
