Some problems with multivariate fast fourier transform. I
have attached the dump of a 30 x 3 matrix that seems to
reliably reproduce these problems
1) mvfft doesn't like vectors. It complains about not having
enough memory:

fft
Hi,
I have problems when calling fft_factor and fft_work directly in my
C-code. Martin Maechler already told me that I should not do this --
anyway, the code works fine if the length of the vector is a multiple
of 2,3,5.
If the length of the vector has different form I get, in some cases, a
segmentation fault when work and iwork are free...

fft fails for lengths 392, 588, 968, 980 .... (PR#1429)
R 1.4.1, Linux and Windows
for(i in 1:1000) {
X <- rnorm(i)
XX <- fft(fft(X), inverse=T)/i
if(max(Mod(XX-X)) > 1e-10) print(i)
}
[1] 392
[1] 588
[1] 968
[1] 980
and I then get a segfault during gc(). The answers are way off, with
imaginary parts 1e10 or more.
These numbers are all multiples of 7^2 or 11^2.
