How bizarre. I changed the BIST test to check that _octave_config_info_ ("version") returns the same string as OCTAVE_VERSION(). Those two things should definitely be equal. See http://hg.savannah.gnu.org/hgweb/octave/rev/e078f5607762.

Fixed. Closing report.

I pulled down the openSUSE source rpm for fftw3. Sure enough, it looks like the double-precision library is built with --enable-sse2 --enable-avx, but the single-precision library is built with --enable-sse2. So yes, on openSUSE they build the single and double-precision variants differently.

Should we try to correct for that, use a substring of the full version string? Should we just ignore it? Should we remove this unit test entirely?

First, I am not facing any obvious problems. Since a while I get the following test error and Rik suggested to report it.

Somehow the "-avx" is cut off in fftwf_version. I run openSUSE Tumbleweed, and have the following installed:
