Is fftw3's current build failure on powerpc the same bug? I've attached
preprocessed source for this; looking at PR target/11949 it seems
similar.

  $ gcc -O3 -fomit-frame-pointer -fno-schedule-insns -fstrict-aliasing -mcpu=powerpc -pthread -maltivec -mabi=altivec -fPIC n1fv_9.i
  n1fv_9.c: In function `n1fv_9':
