My apologies, I was not explicit. The quotes were placed around that phrase because it was picked from the 3.1 beta release notes. There is a serious conflict in using SSE/SSE2/FFTW3.01 and gcc-3.4.[1-3] that was apparently fixed in later versions of gcc.

The new fftw3.1 beta looks good so far.  Final release promised within
next two weeks.

Are you using gcc-3.[23]? If so, it's a bug in gcc.
