Fixed with local s[] in SDCC 2.5.1 #1064.

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.

Tested with MINGW sdcc version 2.4.8 #1004 on Windows XP and
it doesn't crash.

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
