No, as the signal 11 happens on Altivec machines. Which version do you
get an illegal instruction with doing what, under what circumstances? (I
suspect this should be another bug though)

It fails the same way here as recorded in the bug history. Adding
-mabi=altivec to build tests/bench doesn't seem to make a difference
here (I do wonder whether all fftw3 dependants were or will be built
with it though...). Colin, which version of gcc-3.3 are you using? I
noticed I still have the one from testing, not from sid. I wonder which
version the buildd used, might be worth just retrying the build without
changes.
