It is a compiler bug in GCC 4.2.1 with -O3. Try to compile attached unicode.c program with gcc -O3. The correct result is:

$ gcc -O3 unicode.c -o unicode && ./unicode
is ascii? 0
is compact? 1
is compact ascii? 0
_PyUnicode_COMPACT_DATA: 88 vs 88
PyUnicode_DATA: 88 vs 88
explicit cast: 88 vs 88

With gcc 4.2.1 and -O3, you get "is compact ascii? 1".
