FFTW 3.3.10:
* Fix bug that would cause 2-way SIMD (notably SSE2 in double precision)
to attempt unaligned accesses in certain obscure cases, causing
segfaults.
The following test triggers the bug (SSE2, double precision):
./tests/bench -oexhaustive r4*2:5:3
This test computes a pair of length-4 real->complex transforms where
the second input is 5 real numbers away from the first input. That
is, there is a gap of one real number between the first and second
input array. The -oexhaustive level allow FFTW to attempt to
compute this transform by reducing it to a pair of complex
transforms of length 2, but now the second input is not aligned to a
complex-number boundary. The fact that 5 is odd is the problem.
The bug cannot occur in complex->complex transforms because the
complex interface accepts strides in units of complex numbers, so
strides are aligned by construction.
This bug has been around at least since fftw-3.1.2 (July 2006), and
probably since fftw-3.0 (2003).
