Comment (by vbraun):
Some more testing reveals that a) malloc on SPARC is in fact 8-byte
aligned (as specified by the C99 standard), and b) the '''output of
`PyString_FromStringAndSize` is never 8-byte aligned,''' not on SPARC
32-bit, OI 32-bit, Linux 64-bit:
{{{
sage: cython("""
....: def f():
....: cdef char* buf
....: s = PyString_FromStringAndSize(NULL, 1*8)
....: buf = <char*>s
....: return <int>buf
....: """)
sage:
sage: set([ f() % 8 for i in range(100) ])
set([4])
}}}
