This sounds like the following problem, which is fixed in the latest version
(3.3.2) of fftw3:
* Fix incompatibility with Intel icc which pretends to be gcc
but does not support quad precision.
What I don't quite understand is that we tested the code with Intel 12.1.0
and 12.1.1; we need to find out if the problem is really unique to 12.1.2, or
whether some other problem is popping up.
We'll try to get a fix put together as soon as we can. If you have easy
access to an earlier version of the Intel compilers, you might try that.
...thanks for the report....dac
