We're seeing the same thing on a Debian powerpc buildd
https://buildd.debian.org/status/fetch.php?pkg=guile-2.0&arch=powerpc&ver=2.0.11%2B1-9%2Bdeb8u1&stamp=1485708200&raw=0

  FAIL: fractions.test: fractions: (eqv? (expt 2 1/2) (sqrt 2))
  FAIL: fractions.test: fractions: (eqv? (expt 2.0 1/2) (sqrt 2))

and so I wondered if anything new had been discovered since this was
closed.

Note that this 2.0.11 (2.0.11+1-9+deb8u1), which we're attempting to
build to fix two CVEs in jessie.  I can also attempt to manually
reproduce the failure on a Debian porterbox.

Thanks
